Create a set offset from a selected alignment.
Create a set in the current layer connecting points offset from an alignment.
The default horizontal and vertical offsets may be set to non-zero values.
If a VAL is also selected from the Profile View, points are created with elevations interpolated from the VAL, adjusted by the vertical offset, otherwise the points are 2D.
The default HAL is the active alignment, if set. The default VAL is a profile with the same name as the HAL, or a profile which refers to the HAL, if possible.

Filter superfluous points from a DTM.
This is useful for filtering point clouds generated by laser scanners, hydrographic surveys and other large DTMs where much of the data is not significant.
Filter points on spikes, on similar grade and where removal would make insignificant changes to the volume. The filtered points be made moved to layer 0 or made non-contourable, and the point colour is also modified.
- Max Triangle Grade
- Filter out spikes and troughs. If all triangles about a point exceed the enter value and all are either sloping away (peak) or sloping toward (trough) then the point is removed.
- Max Common Side Grade Diff
- Filter out points where the triangles about the point have a Common Side grade range within the value entered. Look at all the triangles about a point and check to see if or grades are within the entered range. If so the point is removed. This filters large triangles of similar grades.
- Max Volume Diff
- Filter points that make a difference to the volume less than the value entered. The volume down to a datum is worked out using just the triangles about a point. The volume is then worked out with the point tested removed. If the volume difference is less than the stated value the point is removed. Filters small triangles with little change to the volume, even with large slope variations.
- Max Effective Area
- Filter points where the total area of all the triangles around the point is less than the value stated. This leaves large triangles unchanged.
- Max Number of iterations
- Reform the DTM and filter again until the maximum number of iterations. If zero, continue until less than 10% is removed in the last iteration.
- Colour of Removed Points
- Set the colour of the filtered points. Points can be then deleted by colour.
- Move Filtered Points to layer zero.
- Filtered points are either moved to layer 0 or made non-contourable.
- Keep Points on Breaklines.
- Protect points that lie on a breakline.
- Keep Points on DTM Edge.
- Protect remove points on the DTM Edge.
- Keep Points > 3 Standard Deviations.
- Protect points that are outside 3 standard deviations from the newly formed DTM surface.
- Generate Report.
- Report to P3Pad.
See also FILTER to filter plines, BLFILTER to filter along sets, GC31 to remove duplicate points and GC53 which changes and identifies non-contourable points. GCGEOCODE is a separate application, which can quickly filter points not close to an average surface model.

Set, clear or list the current active alignment.
- Active alignment
- Select the set or pline to be the active alignment
- Set
- Make the set or pline the active alignment
- Clear
- Clear the active alignment
Active alignments are used for four main purposes:
- Select alignments quickly
- Reference objects to the alignment so that they can derive their chainage properties from the alignment
- Reference objects to the alignment so that during labeling the referenced objects can be replaced automatically
- Control the display visibility of referenced objects
See also GCACTIVE which selects the active alignment from alignments registered in HALMANAGER.
See also REFER which refers objects to an alignment.
PROFILE refers the profile it creates to the selected alignment. Objects in the profile are invisible if the are referenced to alignments other than the active alignment. If the selected algnment is referenced to another alignment, PROFILE will use the chainages of that other alignment.
| Command | UG 125 | Settings\Active alignment | S | 415 |
Set active chainage (station).
Set, clear or list the current active alignment and chainage.
If you selected US English during Terramodel installation, this command is called ACTIVESTATION and the command dialog and Settings menu will refer to Station. If British English, Chainage.
When cross sections are drawn in the cross section view mode using RDX, RDX_GC, XSHEET or XSHEETGC, this command controls which chainage will be displayed. When these commands create the cross sections each object is referenced to the alignment and given the chainage of the cross section as the elevation of the object. Only those objects that are referenced to the active alignment and chainage will be shown. If there is no active alignment or chainage then all cross sections will be displayed, generally on top of each other.
When any command creates objects in the cross section view the current active alignment and active chainage are used to make these objects a part of the cross section. If there is no active chainage or active alignment then any objects created will be displayed in any cross section.
These simple rules enable all cross sections to be created in the same coordinate system (on top of each other) and then viewed one cross section at a time. This allows you to use coordinates of offset and elevation to draw, edit, inverse and so on.
Options- Align
- Select the set or pline to be the active alignment
- Chainage
- Select the chainage along the alignment to be the current active chainage
- Next
- Make the next xline with a larger chainage, along the current active alignment, the current active chainage
- Previous

Create and edit command aliases.
Use command aliases to call commands by command line, menu, toolbar or toolbox button, workspace using names and arguments of your choice.
ALIAS command edits the current aliases. If you use a text editor, changes will take effect when Terramodel is restarted.
ALIAS enables you to substitute for commands which need command line arguments or are unfamiliar, renamed, misspelled or replaced. You can make your own for a local language, dialect, idiom or standard. For example:
| User action | Result | Example of |
| Type UNITSET | Execute UNITSSET | Common misspelling |
| Type FAVOURITE | Execute FAVORITES | Alternative spelling |
| Type FAVORITOS | Execute FAVORITES | Spanish language |
| Type COUNT | Count objects with OLIST | Rename obscure command |
| Type VOLUME | Execute EARTHWORK | Keep Terramodel 9.8 command |
| Execute THREEPC command | Execute GC3PTARC command | Substitute alternative command |
| Click on PROF button in Views toolbox | Open Profile view using SVIEW | Command line argument and toolbox |

| Type 17 | Measure 3D vector using GC29 | Like Geocomp |
| Type DCEDIT | Launch the Trimble DC File Editor | Launch an external application |
| Type CASCADE | Cascade views by "MACROPLAY Cascade" | Execute a macro |
Aliases should be defined in an ALIAS.INI file in the Terramodel Search Path (TSP). The alias.ini installed by the Geocomp Update (...\Terramodel\Geocomp\ALIAS.INI) has over 2000 aliases including French and Spanish commands.
If Terramodel is not finding your aliases, check the search path. If the correct ALIAS.INI is shown in TSP, then check whether there is a list of aliases in TMODWIN.INI. If so, these take precedence, so remove them and restart Terramodel.
Use EXEC in an alias to execute an external command. The maximum argument is 66 characters. If you need to exceed this, see RUN.
You can't alias to an alias, but you can copy the command and arguments using ALIAS command.
To add comments to alias.ini, start the line with a semi-colon ";" so it is hidden in the Alias Editor.

Create breaklines along the arc segments of all sets on a designated DTM layer.
Create points at regular intervals along the arc and connect a set from the existing first TP to each of the new points and finally to the end TP of the arc. The number of chords created is based on a specified maximum middle ordinate (arc-to-chord tolerance) value which indicates the maximum allowable deviation from the true arc for any breakline chord.
The elevation of each point is interpolated along the arc from the elevations of the points at the arc TPs. If either TP has an undefined elevation, Breaklines will not be formed along that arc, and a warning message will be issued in the message area.
The new sets are named "SETARCBL", and given the current line colour, so they can be selected separately from the arcs.

Enable automatic saving of project files.
AutoSave automatically backs up the current project file at a user-specified time interval. Use this feature to protect your work from unexpected power failures or computer difficulties. The autosave file has the same title as your project file, but it has the *.SAV extension. The autosave file is saved in the folder you specify in the AutoSave Configuration dialog box.
To use AutoSave:
- Click FILE, Config System, and AutoSave [AutoSave].
- To turn AutoSave on or off, click the AutoSave On check box.
- To set the time interval for each autosave, type the time (in minutes) between autosaves into the Check Every box.
- To change the directory for autosave files:
- Turn off AutoSave (see step 2), and click Browse. The Browse for Folder dialog box appears.
- Find and click on the folder for the autosave files.
- Click OK. The new folder name appears in the Directory for AutoSave Files area.
- Turn on AutoSave if desired.
- Click OK.
AutoSave is a convenient safeguard for your work. If it does not automatically save your projects as you expect, see if you can determine the cause and resolve the issue yourself.
Recommendations:
- Check to see if you have enough disk space. The drive may be full. If you have little or no room on the disk drive, delete unneeded files, archive old files, or obtain a larger hard drive.
- Check to see a directory used by Terramodel was deleted.
- Make sure your network server is working properly if your computer is on a network.
- If your SAV path is on a network, check if another user has the project file open and it's their autosave file.

Compute volumes by end-area given an alignment, Xlines and two dtm layers
Use this command to compute volumes if you do not have the Site Design or Roadway modules.
Create XLINES along an alignment first. Smaller intervals give more accurate volumes.
Options
- ALIGN
- Enter the alignment (pline or set object) along which Terramodel will compute volumes. Select the same alignment you used to create the xlines.
- OUTSIDE
- Select the first DTM layer from which you will calculate volumes. This layer should completely encompass the second, or inside, layer and must contain 3D points.
- INSIDE
- Use this layer control to select the second DTM layer. Make sure that, within the limits of the xlines, the points on this layer lie within the extents of the outside layer and have elevations.
- CALC
- Specify the chainage limits of the volumes and whether to send the report to the screen or to an external file.
See also VOLUME to compute cut and fill volumes between surfaces, GRIDVOL, GCGRDVOL and GC20 to compute volumes between surfaces within multiple boundaries.
GCGRDVOL can also report volumes within chainage ranges so it can give a similar report to AVGEND but with more accurate volumes.

Draw a curve of best fit through a series of selected points.
Create a pline arc fitted through three or more points using the Least Squares method.
Best-fit curve options:
- SELECT POINTS
- Select the points through which a curve will be fitted.
- OPTIONS
- Select layers for the points and curves, set the location method and vary the weight of each point in the computations.
- LAYER
-
- Store points on
- Specify the layer on which the PC, PT and radius points will be stored when using the Create option.
- Store curve on
- Specify the layer on which the set arc that connects the PC, PT and radius points will be stored when using the Create option.
- LOCATION METHOD
-
- Auto select/User select
- Auto automatically calculates the beginning point. User lets you enter a beginning point. When you select User, you can enter a trial location for the centre of the radius and the radius length. Bfitcurv uses the first three points to determine an initial location for the radius point and the radius length, then uses an iterative process to find the solution. If, with the Auto option, Bfitcurv suggests an arc in the opposite direction than desired, try again with the User option. Guessing a radius point and length close to the true answer will speed the calculation process.
- Radius center
- Select a trial position for the calculation of the true radius center.
- Radius length
- Select a trial radius for the calculation of the true radius.
- NUMBER
- Lists the points you selected and through which a curve will be fit. From this box, you can select a point and edit its weight of importance. When you highlight a row in this list box, its corresponding weight will appear in the Weight box for you to change.
- POINT
- Display the selected point numbers.
- WEIGHT
- Set the weight of importance of each point through which the curve will pass. Bfitcurv will ignore any points having a weight of zero. A high weight will force the arc to go through the point. If fewer than three points are given a high weight of importance, Bfitcurv will not find a valid solution. When three points are given a high weight, an arc is passed through the three points.
- LOCATE
- Show the solution by creating a pline circle with the computed radius point and radius distance. In some situations, it may take several minutes to calculate the solution.
- CREATE
- Create a set arc, PC point, PT point and radius point.
- REPORT
- List the points used to calculate the arc, the weight of importance of each point, their distances from the arc and their coordinates on the arc perpendicular to their position.
- DELETE
- Delete the last set and points created with the Create option.

- Lists the points you selected and through which a line will be fit. When you highlight a row in this list box, its corresponding weight of importance will appear in the Weight box for you to change.
- POINT
- Display the point numbers of the points whose weight will be edited.
- WEIGHT
- Sets the weight of importance of each point through which the line will pass. A weight of zero will force the line to go through the point. When two points are given a weight of zero, a line is passed through the two points. To ignore a point remove it from the selection. Higher weights pull the line towards the point.
- CREATE
- Create a set line and two points showing the solution.
- REPORT
- list the points used to calculate the line, their weight, their distance to the line and their coordinates on the line perpendicular to their position.

Create an elevation view of points.
Copy selected points into an "Elevation" drawing in View 6.
The position of the point along the selected Baseline determines the horizontal position in View 6, while the Z coordinate of the Point determines the vertical position in View 6.
The points in View 6 are placed on the same layer that the points were originally placed on in the Plan View.
The points in View 6 are given an alphanumeric identifier (point number). If the baseline has a Name, then this name and the original identifier are combined to create the identifier for the point in View 6. If the baseline does not have a name, a (2) is combined with the original identifier to create the identifier for the point in View 6.

Filter excess points from breaklines.
Replace sets on the selected layer with sets made up of straight segments within a filter "tube". This will usually reduce the number of vertices for sets containing straights and increase the vertices for arcs.
The initial filter tube is of the specified length and orientated to the first segment on the set with width perpendicular to the segment and height measured vertically.
You can limit by multiple boundaries.
BLFILTER checks for additional vertices that are contained within the limits of the filter tube. Any vertices inside the tube are discarded. The first vertex Terramodel finds outside of the tube is kept, and the last discarded vertex inside the tube is added back to the set. The tube is then reoriented based on the last two vertices, and the process is repeated.
Filtering is similar to FILTER command, except that BLFILTER also tests for elevation tolerance.
SETFILT and GCFILTER filter by 2D offset tolerance instead.
See also ARCBL which adds points and breaklines points into arcs and 3DFILTER which filters insignificant points from a DTM.

Check for crossing sets on a layer.
Wherever sets on the selected layer cross, create a point with the name "bl-cross" on layer CROSSING and labelled with symbol 40 (circle).
These points give an indication of crossing breaklines.
Some points may be created at set segments which are not breaklines, such as arc segments or sets with points that are 2D, non-contourable or on different layers.
Any previously created points on layer CROSSING will be deleted.
As each set is checked against all the other sets, the count will appear slower at first then speed up.
Use CROSSCHK to check all selected sets or plines.

| 01/09/11 | Draw\Block\Reread block | S |
Create, place, list or delete blocks.
Combine objects into a single object that can be manipulated as a block.
Blocks can consist of points, sets, plines, dynaviews, text and other blocks. Objects in blocks do not retain layer names or point numbers. Sets become plines.
The block can be inserted multiple times into projects, shared between projects, scaled, rotated and otherwise edited.
You can create both internal blocks (which can only be used within a single project file) and external blocks (which can be referenced by any Terramodel project file). If you specify an External block, Terramodel will use the first block with that name on the Terramodel Search Path.
Block Options
- CREATE
- Create a block definition, given a group of objects and the origin of the block. Use the Name button to enter a block name of up to 15 characters, a description, and define it as an internal block or external block with .BLK file extension.
- SETTINGS
- Establish default parameters used when inserting blocks.
These block settings apply to all subsequently created blocks.
- SCALE
- Enter a scale factor for the X, Y, and Z dimensions of all inserted blocks. The factors are measured in relation to the sizes of the original objects. For example, if you want to place a block 2.5 metres in diameter, and the block you are placing is 1 unit in diameter, use a scale factor of 2.5.
- ROTATION
- Establish the amount of clockwise rotation for the X, Y, and Z ordinates of each inserted block, rotated about the insertion point.
- INTERNAL/EXTERNAL radio buttons
- Specify whether all blocks are to be created as internal or external.
- AUTO SCALE
- Apply the current drawing scale of the active view to the block insert. Use this feature when you want to keep the plotted size of the block the same regardless of the current drawing scale. One example would be a north arrow that you always want plotted 4 inches high regardless of the drawing scale.
- AUTO ROTATE
- Cause blocks to rotate automatically through a dynaview as the dynaview is rotated. This should not be used with a north arrow but could be used with other symbols to keep them oriented upright on the final plotted sheets.
- CLIP
- Clip the block to the limits of rectangular dynaviews, even if the insertion point falls outside the dynaview. Clipping complex blocks such as hatch patterns can cause the screen redraw speed to decrease.
- MAP COLOUR
- When a block is inserted, it is assigned the line colour of the current layer.
This block colour is retained if the block is later relayered.
- ON
- All objects within the block are drawn with the colour of the block.
- OFF
- The objects in the block are drawn with their original colours. Blocks which contain block objects with colour 0 are drawn with the colour BYLAYER.
- EDIT
- Edit the attributes of an inserted block.
- LAYER
- Lists the available layers, where you choose one on which to place the block.
- COLOUR
- Modify the colour of the inserted block.
- ATTRIBUTE
- List any attributes that have been attached to the block. Any attributes must be edited using specific commands.
- GROUP
- Modify the integer group number. Set 0 for no group.
- REF. OBJ
- Specify record number of a parent object to which the blocked is referenced.
- OBJ
- This area displays the record number of the block.
- NAME
- Modify the name of the block to match another available block. For example, if you change the name of a block named CIRCLE to TREE1, the circle block will be replaced with a tree canopy block of different size.
- DESCRIPTION
- Displays the description you assigned to the block definition when you created it.
- ORIGIN
- Modify the X and Y of the origin of the block.
- ELEV
- Modify the elevation of the block. See PN below.
- SCALE
- Modify the X, Y or Z scale of the block.
- ROTATION
- Modify the X, Y, and/or Z rotation angles of the block.
- AUTO SCALE
- Apply the current view scale so the block is always the same size on the plot. Auto scale is off by default. Use SCLBLKS to turn Auto scale on.
- MAP COLOUR
-
- ON
- All objects within the block are drawn with the colour of the block.
- OFF
- The objects in the block are drawn with their original colours. Blocks which contain block objects with colour 0 are drawn with the colour BYLAYER
- AUTO ROTATION
- Cause block objects to rotate automatically through a dynaview as the dynaview is rotated. This should not be used with a north arrow but could be used with blocks that oriented to the top of final plotted sheets.
- PN
- When a subject point number is specified the block origin is computed relative to the coordinates of the point. When the point is deleted any attached block will also be deleted. EAT text in the block can refer to the subject point.
- INSERT
- Insert a block into a project file.
- Block name
- Specify the name of the block you want to insert. Pick from a list of blocks already inserted in the project, or type in the name of a block in the Terramodel Search Path.
- LOC
- Locate the origin of the block.
- SCALE
- Set the size of the block relative to the size of the block definition. Most blocks are defined as one unit high so the scale you enter becomes the height of the inserted block in the units of the view. Note that the CIRCLE block is one unit in radius, and point label blocks vary in height as specified.
- ROT
- Enter the rotation of the block around the origin.
- MAP COLOUR
- When a block is inserted, it is assigned the line colour of the current layer.
This block colour is retained if the block is later relayered.
- ON
- All objects within the block are drawn with the colour of the block.
- OFF
- The objects in the block are drawn with their original colours. Blocks which contain block objects with colour 0 are drawn with the colour BYLAYER
- INSERT
- Insert the block once you have set the location, etc.
- LIST
- List the internal and external blocks contained in your project file. The list includes the block name, whether it is an internal or external block, the view in which the block was created, the number of lines (polylines or sets) contained in the block definition, the number of text objects contained in the block definition, the number of inserted blocks of that block definition, and the description of the block.

- Pts
- Select the points.
- SCALE
- Set the size of the block relative to the size of the block definition. Most blocks are defined as one unit high so the scale you enter becomes the height of the inserted block in the units of the view. Note that the CIRCLE block is one unit in radius, and point label blocks vary in height as specified. Also enter the rotation of the block around the origin.
- MULTIPLE
- Insert the blocks on each selected point.
- PURGE

Label objects with predefined callout text.
Create, edit, store and use predefined callout styles to label common features.
Quickly label common point and line features, such as kerb inlets, without having to type the text each time.
Stored callout styles define text in the label and may also define leader lines and text borders.
Predefined the callout styles save time, look consistent and reduce typing errors.
Callout styles are stored in multiple external .COS libraries in the ..\Terramodel\Locale\English and ...\Terramodel\Geocomp folders in categories. The loaded styles are recorded in tmodwin.ini and therefore independent of the project. The Geocomp Update loads the geocomp01.cos callout style library.
Callout Options
- CALLOUT
- Create or edit a callout style, load and clear the styles contained within an external callout style library (.COS) file, and select the callout style to be used.
- HAL
- If the callout style contains EAT codes for chainage and offset, refer the callout text a horizontal alignment.
- LDR / SUBJ
- If the the callout style contains EAT codes for a subject, refer to that subject. If the callout style includes a leader line, pick the leader line location.
- LOC
- Enter the insertion point of the callout text. Once you have entered the insertion point location, the coordinates will appear in the Loc box. If you pick a location graphically, the text will be placed. If you enter the coordinates in this control, click on the Text control to place the text.
- ROT
- Enter a bearing or an angle of rotation (measured from due north) at which the text is to be placed. Valid rotation angles range from 0° to 360° and can include negative angles. The default rotation is 90° which generates horizontal text.
- PROPS
- Designate a leader line style and a border style and their properties. You can also edit the text object's subject record and its subject HAL record from within this dialog box.
- TEXT
- Place the text once you have typed it and set the other text parameters to your liking.
See also Gc21 which sets the active callout style.

Recentre views based on chainage.
Tile the Plan, Profile, Super and Xsect views and centre by chainage from a selected roadjob alignment.
Ideal for working along a long narrow alignment such as a road, rail or pipe.
For any selected roadjob, nominate a chainage by selecting a location in the plan, profile, super or xsect views. The plan, profile and super views, if open, are recentred on the horizontal or vertical alignment at the selected chainage. The active chainage is set to the nearest cross section, and the Xsect view is fitted to the data.
If the selected view is the Xsect, the active chainage is used, if set.
The match button uses the centre of the active plan, profile or super view to recentre the other views. If the profile view is active, the plan and super views are scaled to fit the chainage range.
There are buttons to zoom in or out by 25%, to fit data in all four views, and to move to the next or previous chainage then making it active.
On starting this option, the views are horizontally tiled.

Replace characters in names based on a dictionary.
Replace characters in names of selected records within a range according to a selected dictionary.
Create a dictionary file using a text editor, following this example:

Note that the changes are processed in dictionary file order, so be careful. If, in the example, 'CH' replaced was before 'CHAINAGE', you would get 'PKAINAGE', not 'PK'.
If the new text is a different length, you can match the text width attributes to suit.
You can also refer to characters by their three-digit decimal ASCII value. For example, \010 for new line and \176 for degree (°) sign. What you see depends on the font. Not all fonts contain all characters. For example, in some fonts degree sign is \127. In fonts such as symbol.fnt, you can specify a symbol by this method.

Similar to JOIN, except that if the lines do not have to have coincidental end points a connecting line segment is added.
The resulting line will retain the record number of the first line selected, and all of its properties and attributes. Any objects that previously referenced either the first or second line will thereafter reference the resulting line.
In selecting the lines you can pick anywhere on the line. However, you must pick nearest the end that you wish to be connected to the other line.

Extract pline contours from a DTM.
Create plines interpolated from a DTM at elevation intervals.
The intervals, labelling, linetypes and layers are controlled by CONTOURSET.
| Command | DTM\Contour | S | 289 |
Create plines at a specified contour elevation.
Create contour plines everywhere a specified elevation intersects a specified DTM layer.
The labelling and minimum length are controlled by CONTOURSET.
| Command | DTM\Generate contours at elev | S | DTM 4 |
Configure contour settings.
Set the contour values uses by commands such as CONTOUR, LINKSET, COLORPT and COLORCON.
- Normal interval
- Contour elevation increment
- Index interval
- The number of normal intervals per index contour
- Label nth contour
- The number of normal intervals per labelled contour which is usually the same as the index interval
- Splining
- B-Splines pass inside the contour control points (IPs) and Overhauser curves pass through the control points.
- Layer Assignment
- If the contour and index contours layer names include *, the * is substituted by the DTM layer name.
- Exponential
- Create contours of exponential surfaces such as bacterial concentration or corrosivity.
- Depression contours
- Create the lowest contour line using "Depression" linetype.
See also CONTOURATELEV.
| Command | Settings\Contour settings | S | 43 |
Compute volumes from contour plines.
Computes volumes for individual mounds or depressions based on contour plines.
The volumes are obtained by using the average-end-area method, where the area of a closed contour is determined, then averaged with an adjacent contour, and multiplied by the contour interval to obtain an incremental volume. Incremental volumes are then added together to obtain a total volume.
This method is less accurate than that of the EARTHWORK command, but can provide an alternative approximation of mound and depression volumes.
You can use the ContourVol command in two different modes:
- Line
- Select a series of closed contour plines representing a mound or depression. Click the Volume button to display the accumulated volume in the message scroll area. If you wish to display a more detailed report that can be saved or sent to a printer, click the Report button.
- Digitizer
- Digitize closed contours representing a mound or depression.
- Input the elevation of the first contour using the Elev elevation control.
- Digitize a series of points for the first contour using the Loc point control. You must provide a minimum of three points for each contour.
- If you select points by typing coordinates in the Loc point control, click the Pt. button to enter the point and proceed to the next point.
- When you are done digitising points, click the End button to close the contour.
- Repeat for successive contours until you have defined the mound or depression.
- Click the Report button to display a detailed report that can be saved or sent to a printer.
The selected contours must be closed, assigned an elevation, and form a continuously rising mound or a continuously falling depression. If the contours are open due to labels, use GCMATCH to create plines across the gaps, then JOIN the contours.

Convert sets to plines or plines to sets.
Any combination of sets and plines can be converted to a single type of object. New lines are assigned the colour and linetype of the original line and placed on the layer of the original. Names, start chainage and other attributes are not retained. You have the choice of keeping or deleting the original objects.
Convert Options
- Lines
- This select control is used to select the lines to be converted
- To (Set or Pline)
- These radio buttons are used to select the type of lines to be created
- Del old
- This check box is used to optionally delete the original lines
- Dup pts ok
- This check box lets Terramodel create points for new sets that have duplicate northings and eastings (point numbers cannot be duplicated)
- Lay
- This check box lets you set up the default behaviour for placing the new entity on a layer. When this box is checked, Terramodel places new entities on the current layer. When this check box is not checked, Terramodel places new entities on the same layers as the original objects.
Tips on using Convert
- GCCONVRT
- By default, the Geocomp Update aliases CONVERT to GCCONVRT so as to retain all the attributes such as Name, Layer, etc.
- Dup pts ok
- CONVERT can take a long time to convert a lot of plines to sets, especially if "Dup pts ok" is OFF. It is much faster to convert with this ON, and even faster to use GCCONVRT.
- Duplicate point removal
- Use DTM formation or GC31 instead of CONVERT to remove duplicate points.
- Elevation
- When converting a set to a pline, the elevation of the new pline is derived from the first point in the set.
- Spirals
- Terramodel uses sets and plines for specific purposes. For example, sets cannot include spirals and plines do not link points and cannot be labelled with lot numbers. See the Terramodel User Guide for more information about object types.
- Visibility
- When converting sets to plines, hidden segments are omitted so the plines are split. To temporarily display all hidden set segments use DISPLAYSET Ignore hide. To hide or reveal hidden set segments use HIDE. To permanently reveal all hidden set segments of selected sets, use UNHIDE.
- Arcs
- When converting a pline to a set line, a new point object is created for the radius point and at each PC and PT. If multiple arcs use the same arc points, duplicate points will be created at each arc point.
- Design
- When creating a design, it is best to begin with construction lines that can easily be changed to accommodate changes in design concept. Plines are excellent construction lines because they are very basic, two-dimensional objects having a large amount of flexibility in their use. After the initial concept has been stored and modified, you can convert the plines into set lines, then assign elevations to the endpoints. You then have a design with intelligence whose surface can be modelled and from which volumes can be calculated.
| Command | Edit\Convert | S | 292 |
Set slope convention.
Define the slope convention (ratio preference) according your local practice.
Choose either Horizontal run: vertical rise (e.g. 4:1) or Vertical rise: horizontal run (e.g. 1:4).
These conventions can be overridden by Terramodel settings or report formats. Even within the one project, the convention may vary, so check in each case.
| Command | Settings\Convention settings | S |
Coordinate transformation of points.
Use either seven-parameter transformation, or where possible, the faster and more accurate NTv2 distortion grid method.
The principles and operation are described in detail in Terramodel 10 User's Guide Chapter 13: Using Coordcon.
See also our Nav notes for more background and examples of how to create, set up and use coordinate systems.
COORDCON may be aliased to GCCOORD which transforms not just points, but sets, plines and text. GCCOORD also adds Australian and New Zealand Coordinate Systems.
GCLLGRID draws Latitude and Longitude grids and labels using COORDCON settings.
GeoCalc transforms files of points, whereas COORDCON transforms points in Terramodel projects.
Both COORDCON and GCCOORD use the same COORDSYS, DATUMS and ELIPSOID data files in the \Shared\Mentor.dir.
COORDCON requires COGO module.
If you are converting between foot and metre coordinate systems, use MEASUNIT to set the project metric conversion factor for International foot (0.3048) or US Survey foot (0.304800609601).
CSMAN and GEOSYS are part of a completely separate Coordinate System Manager for Trimble devices only.

Toggle and configure the Coordinate Scroll display dialog.
Coordinate Scroll tracks the cursor. The data displayed varies depending on the current command, the current control type (locate, bearing, distance, offset, station, point, etc.) and the active view mode (plan, profile, sheet, cross section, etc.).
Coordinate Scroll Options
- COORDINATES
- When the cursor is in the plan view mode it displays its Northing and Easting. In the profile view it displays the station and elevation. In the cross section view it displays offset and elevation, and in the sheet view, X and Y.
- GPS COORDINATES
- Reserved for future use.
- 3-D DIGITIZER Used when the digitizer responds with X, Y and Z values.
- DELTA COORDINATES
- Shows the change in coordinate values from the anchor point to the rubber band cursor in the current view mode units.
- BEARING-DISTANCE
- Shows the bearing and distance from the anchor point to the rubber band cursor when in the plan view mode. In the profile or cross section views it shows the grade and distance.
- CHAINAGE( or STATION)-OFFSET
- With a rubber band cursor and an active chainage control, the chainage and offset relative to a selected alignment is shown in the plan view mode. When the cursor is rubber banding in the plan view, a single line showing the chainage will be shown in profile view and the offset in the cross section view. When rubber banding in the profile view mode the chainage and the difference in elevation from the selected alignment to the cursor is shown.
- LAYER-ELEVATION
- Shows the current DTM layer and the elevation on the DTM at the cursor location. Set the current DTM layer first using DTMCH, SPOTSPOT or some other command that requires a DTM.
- SLOPE-ASPECT
- Shows the slope of the TIN on the current DTM layer at the cursor location and the direction of the surface slope. This option must be used in conjunction with the above layer-elevation option, to establish the current DTM layer.
- VISIBLE
- Controls the visibility of the coordinate scroll.
- SAVE
- Saves the current settings to the TMODWIN.INI file and exits the command.
- DONE
- Keeps the current settings for the current session without updating the TMODWIN.INI file and exits the command.
Coordinate Scroll tips:
- Use the title bar to drag the scroll to a new location.
- Minimize the scroll to an icon by clicking its minimize button.
- Maximize the scroll by double-clicking the minimized Coordinates icon.
Coordinate Scroll TMODWIN.INI settings:
- Under [CoordScroll], CoordNdec=x controls number of decimals for CoordScroll display and digitizer precision of a graphically entered point.
If you have multiple displays, Terramodel, and the coordinate scroll if visible, will always open on the primary display, but it is possible to lose the scroll of the edge of the display. If you lose the scroll, check that you have turned it on. If you can't find it, type RECOVERSCROLL.

Copy selected objects to a new location or layer.
Duplicate selected objects.
- 3d
- If ticked, you can specify the From and To coordinates as X,Y,Z, rather than X,Y.
- Lay
- If ticked, copy the objects to the current layer, otherwise they remain on the original layers.
- From
- Specify the location from which the vector is to computed
- From
- Specify the location to which the vector is to computed
Tips
- The coordinate order is controlled by VIEWSET.
- To duplicate objects in a new location, when you know the coordinate shift, enter 0,0 (or 0,0,0 if 3D), in "From" and the relative dX,dY(,dZ) in "To".
- To assign starting point numbers for new points, use the "Start Pn" setting of POINTSET.
- The COPY command can modify properties of the duplicate objects including colours, names and contourability, unlike GCCOPY.
- To copy objects to another layer, such as a DTM layer, without changing their location, use GCCOPY instead.
- To make multiple copies, use MULTICOPY.

The grade is applied in 3D from the set. This is different to simply grading to an offset and elevation. If the set has a steep longitudinal grade, the difference will be noticeable.
Whenever the Design command encounters an arc on the outside edge of the design DTM, it uses the Segments Per Arc setting of DISPLAYSET to break the curve into straight line segments. Points are created at these segments (along the curve) and are then projected to intersect with original ground. Set lines are created to connect the design curve points and the ground intersection points.
Ground intersection points, points along arcs, and sets that Terramodel creates are assigned the name of the design layer as their name. You can easily erase these points by selecting them by name. (Name selection is case sensitive.)

Modify elevation to design roadway elevation.
Modify the elevation of existing points so that they lie on the design surface of a designated road job.
Terramodel projects a perpendicular intersection from a location to the HAL to determine the chainage along the HAL and the offset from the HAL. The elevation of the point is interpolated by cutting a slice through the design surface at the station and offset.

Configure design settings
Configure the default batter slopes and smoothness assigned to new sets and vertical sight distance calculation parameters. These settings are stored with the project file.
- Tie-in slopes
-
- Cut slope/Fill slope
- These vertical controls let you enter values for cut and fill slopes that will be assigned to newly created sets. The tie-in slopes are used by DESIGN to project the design DTM onto the existing ground DTM. Any change to these values will change the slope of all sets, except sets where the slopes have been fixed by EDIT.
- Default set smoothness
-
These options let you establish the set smoothness that is applied to sets as they are created. Use Soft for the default unless you gave a good reason to change it temporarily. Smoothness can affects contour, cross section and profile plines, and surfaces in TVLITE. Use SETSMOOTH or to change the smoothness of selected sets.
- Soft
- Contours illustrate relatively smooth transitions, such as in natural features. When the contour line passes through the set line a single vertex is created before the line is smoothed.
- Hard
- Contours bend more sharply around breaklines. When the contour line passes through the set line, two vertices are created before the line is smoothed.
- Sharp
- Contours depict abrupt changes in a pline where it crosses a breakline. This smoothness is used for such features as curbs and gutters or edges of concrete pads. When the contour line passes through the breakline, three vertices are created before the line is smoothed. If all breaklines are Sharp, TVLITE can be very slow.
- Dead
- Contours will not be drawn inside of a closed set boundary line. This smoothness is used where contours inside of building footprints and ponds would be undesirable. The DTM still extends through the dead area but the contour lines are removed from inside the area. Cross section and profile plines are also suppressed in dead areas. Use dead smoothness for specific sets, not the default, otherwise contours will be completely suppressed inside DTMEDGE sets.
- Vertical Curve Design Controls
- Set the eye, object, and headlight distances that Terramodel will use when calculating the sight distances used for computing vertical curves based on AASHTO standards.
- Eye Height
- The distance from the road to the standard eye height of a driver.
- Object Height, Stopping:
- The distance from the road to the standard object height for computing the safe stopping distance.
- Object Height, Passing:
- The distance from the road to the standard object height for computing the safe passing distance.
- Headlight Height:
- The distance from the road to the centre of the standard headlight beam.
- Divergence Angle:
- The angle of the standard headlight beam divergence.

Label dimension between two points or a segment of set or pline.
You can dimension between two points or along a segment with text placed at a location.
Click Props to configure the labelling units, decimal places, and layer on which the labels will be placed.
-
General properties
- DISTANCE TYPE (LINEAR/HORIZONTAL/VERTICAL)
- Dimension the whole distance (Linear), or just the Horizontal or Vertical distance. In the plan view, Horizontal will dimension the change in the Easting coordinates, and Vertical will dimension the change in Northing coordinates between points or of the segment.
- LAYER
- Selects the layer on which to place dimension lines and text. If you select layer 0 (zero), Terramodel will use the current layer.
- DIMENSION BLOCKS
- Check this to store each dimension as a block. Dimension blocks are named dim n, where n is a sequential number. If you delete a dimension block object, Terramodel discards the block definition when the project is saved.
- FORCE DIMENSIONS OUTSIDE
- Check this box so that the arrows on the dimension lines point inward, when the text is placed outside of the extension lines. When this box is not checked, dimension line arrows point in the same direction when the dimension text is placed outside the extension lines. This option is not implemented when you locate the dimension labels within the extension lines.
- FORMAT (ENGINEERING/ARCHITECTURAL)
- The Engineering format uses decimal project units (feet or metres) set by MEASUNIT. The Architectural format labels the text in feet, inches and fractional inches.
- UNITS SUFFIX
- Append this suffix to the end of the units labels. The number of characters you can enter in this control is dependent upon the font you are using.
- SUB-UNITS SUFFIX
- Append this suffix to the sub units (sheet units) portion of the label. Terramodel only uses sub units when dimensioning in the Architectural format. The number of characters is dependent upon the font.
- NUMBER OF DECIMALS
- Denote the precision for distance labels using the Engineering format.
- Units Scale
- Enter the factor for the calculated distance. For example, to convert feet to inches, enter 12.0.
- FRACTIONAL INCREMENT
- Select the precision of the Architectural format dimensions.
-
Text Properties
- TEXT STYLE
- Select the text style for font, height, aspect, and slant of the dimension text. The justification of the dimension text will always be Center-Middle, and the orientation will always be Legible.
- TEXT COLOUR
- Specify the colour for the dimension text.
- DISTANCE FROM TEXT TO LINE
- Enter a factor for the text height to determine the distance the text is placed away from the dimension line. If the dimension text is located to either side of the dimension line, this determines the distance from the dimension line to the beginning or the end of the text.
- DRAW TEXT ABOVE DIM LINE
- Place dimension text above the dimension lines or even with and between the dimension lines.
-
Line Properties
- DRAW DIMENSION LINE
- Enable dimension lines.
- LINETYPE
- Select the line type to be applied to the dimension line (usually a LEADER LINE).
- COLOUR
- Specify the colour for the dimension lines.
- DRAW EXTENSION LINE 1
- The Segment option creates and orders each pair of extension lines (dimension lines located outside of the dimension limits) based on the direction of the segment. Checking this box causes Terramodel to create the first extension line.
- LINE TYPE
- Select the line type to be applied to the first extension line.
- DRAW EXTENSION LINE 2
- Create the second extension line.
- LINE TYPE
- select the line type for the second extension line.
- COLOUR
- Specify the colour for both extension lines.
- LENGTH OF OUTSIDE LINES
- Define the length of the outside dimension line in sheet units. This option is enabled only if you check Force Dimensions Outside and locate the dimension text outside the extension lines.
- EXTENSION LINE GAP
- Defines the offset (in sheet units) from the limits of the distance you are dimensioning to the beginning of the extension lines. If a dimension line begins within this gap area, the extension line at that location will be twice the gap value plus the height of the text, centred on the location.
When the dimension is created in a view with a vertical exaggeration, the dimension text will appear distorted if the view exaggeration changes.

Control how objects are displayed.
Allows some objects to be partially displayed for quicker display redraw times.
Controls the number of pixels used to display points.
The view resolution segments per arc, spline, spiral and vertical curve controls not only the resolution on the display but also profile extraction from a DTM and similar functions.
For any curve, the maximum number of segments for all the components of a curve together is 100 otherwise the curve will not display correctly. For example, if arcs have 20 segments and spirals have 10, the total for Arc curves would be 10+20+10=40, and the total for Combining curves would be 10+20+10+20+10=70.
PLOTSET maintains an independent plotting resolution that enables you to plot curves to the plotter more smoothly than is generally required for display.
- View Resolution Segments per
- All curves are displayed as a series of short straight line segments, but maintain their full mathematical properties for computations. The greater the number of line segments the smoother the curve will appear, however the time it takes to draw the curves and the amount of memory required increases with the number of segments. All curves are saved with a view resolution of zero to minimize file size. The view resolution settings are also used when translating objects to other file formats.
- Segments per Arc
- Set the number of segments per circular curve. The 10 or above will make most arcs appear smooth unless the radius is large.
- Segments per Spline
- Sets the number of segments per splined pline. Splined lines are used primarily for contour lines. The recommended setting for most applications is 3. A setting of 0 displays the line as unsplined. A setting of 1 is invalid and will be drawn as a setting of 2. The maximum setting is 100.
- Segments per Vertical Curve
- Sets the number of segments per vertical curve. The recommended setting of 10 will make most vertical curves appear smooth.
- Segments per Spiral Curve
- Sets the number of segments per spiral curve. The recommended setting of 10 will make most spiral curves appear smooth.
- Quick dynaviews
- Toggles the display and plotting of objects through dynaviews. When toggled on, objects displayed through dynaviews will not appear within the dynaviews. Only the dynaview frame will be visible. This option speeds display and plotting when the objects drawn through the dynaview need not be viewed. This is particularly helpful when you are arranging dynaviews within the Sheet view mode.
- Quick text
- Toggles the way text objects are displayed and plotted. When toggled on, all text objects are displayed and plotted as text boxes. The text boxes will be drawn to the limits of the text objects and can be used to select and manipulate the text objects. When toggled off, text objects are displayed and plotted normally. The Quick Text setting does not affect the display and plotting of attribute text.
- Quick EAT codes
- Toggles the way embedded attribute text (EAT) codes are displayed and plotted. When toggled on, all EAT codes are displayed and plotted as the actual codes and not the interpreted value. When toggled off, EAT codes are displayed and plotted as the interpreted value.
- Quick linetype
- Toggles the way linetypes are displayed and plotted. When toggled on, all linetypes are displayed and plotted as solid lines, making both the display and plotting of lines faster. When toggled off, linetypes are displayed and plotted using their full definition.
- Ignore hide
- Toggles the way hidden set segments are displayed and plotted. When Ignore Hide is on, set segments hidden by HIDE are displayed and CONVERT converts hidden set segments to plines.
- Hold DV scale
- Toggles the way attribute text and the linetype scales are displayed and plotted within dynaviews. When toggled on, attribute text and linetypes are scaled within the individual dynaviews in which they are displayed, based on the scale assigned to the dynaview, as opposed to being based on the plot scale of the viewing mode in which the attribute text or line is drawn. This allows you to create multiple dynaviews showing the same object or even of the same viewport at varying scales. In this case, the attribute text and linetypes appear in accordance with their definition, regardless of subsequent alterations of the plot scale of the viewing mode in which these objects are drawn. When toggled off, attribute text and linetypes as displayed within a dynaview, are scaled based on the current plot scale of the target viewing mode, and their appearance will change as that plot scale is altered. Text objects are not affected by this setting. If a text object is smaller than the number of pixels set in the Text Box Size option of the Display Settings dialog box, it will also appear as a text box.
- Drag Text Quick
- Drag Text Quick sets the way text is displayed when you drag it. When its check box is checked, it distorts the text so the text can be dragged quickly. When its check box is not checked, it displays the text so you can read it when you drag it, which slows the process.
- Point size
- Set the size in pixels for a cross symbol for for each point. For many high resolution graphics cards, point objects drawn with two or three pixels will enable you to see the points on the screen more clearly.
- Text box size
- This integer control sets the number of pixels used to determine when a text box will automatically be drawn.
Text objects and attribute text that are smaller than the number of pixels you enter will be displayed as a text box.
This setting speeds screen redraw by quickly drawing text as a box when it is too small to read on your display.
If you set the text box size to 0, Terramodel will always draw the text characters.
The Quick Text option displays your text as text boxes regardless of the height of the text in pixels.

Drafting settings.
Configure the text spacing, text offset distance, and other general drafting settings for the project.
- Flip over angle
- Configure the angle when attribute set segment labels are automatically flipped so that they can be read from left to right, from the right-hand side and the bottom of the sheet. Valid entries for this parameter are from 0° to 45°. If the value is set to 45°, the label will be upside down if read from the bottom of the sheet, but will appear correct when read from the right-hand side of the sheet. The angle should generally remain at 0° or 10°. This angle is applied to each dynaview so that the same labels can be oriented properly through multiple dynaviews.
- Text clip margin
- Set the amount of space around text objects, for CONTOUR, CLIP and HATCH when clipping lines to text. Typical values range from 0.3 to 0.5 times the height of the text object. This value also controls the spacing between text and its associated text border, with the exception of the Underline border style which uses the following offset distance value.
- Offset distance from line/arc
- Set the distance between a line or curve and its label. This value also controls the offset between the line generated by an Underline text border style and the first and second lines of text when that style is used. Typically, enter a value at least twice the diameter of your largest pen.
- Space (%) between lines of text
- Establish the spacing between lines of attribute text or lines of text objects. A typical value is 50% of the text height.
- Fixed Detail Border Size
- Configure the fixed height for all text borders with a Detail border style. Borders with other text border styles, vary in height according to the limits of the text and the above text clip margin.
- Text Line Colours
- Configure the colours for leader lines and borders associated with text.
These global settings affect all text in the project file.
- Leader Lines
- The colour for text leader lines
- Underlines
- The colour for all text borders with Underline text border style
- Margin Lines

Report planimetric and surface areas of a DTM within slope ranges.
Report planimetric and surface areas of a DTM within slope ranges to the P3Pad report editor.
The slope ranges for which areas are to be reported are defined in the [Slope Table] section of the TMODWIN.INI file.
This table can be manually edited to configure a maximum of 100 slope ranges (by default 16).
To set the number of slope ranges, edit the TableSize=# variable. The lines in tmodwin.ini following TableSize define each slope range with boundaries defined by decreasing percentage slope.

Create a set around a DTM edge.
The set is on the DTM layer in the current colour.
The current link settings determine the extent of the DTM.
The DTM edge set locks the extent of the DTM, even against changes in link settings.
Multiple contiguous sets around a DTM will still function as a DTM edge, but allow DESIGN and MOVEPAD to use variable batters.
You can edit a DTM edge set using BREAK, SET and so on.
If there are any 3D points on the layer outside the DTM edge set, the DTM edge is invalid. GC22 checks for and fixes this.

Match overlapping DTMs at a match line.
This process is typically required two merge two DTMs created by photogrammetry.
By matching the DTM layers, contour lines will match perfectly at the user specified match line. Alternatively the contour lines can be relayered and joined using JOIN. See also GCMATCH which matches contours only and GCMERGE which merges multiple DTMs.
- DTM
- Select two DTM layers to be matched
- LINE
- Select a pline along which the DTMs are to be matched
- DEF
- DTM Match Defaults dialog box
- NORMAL MERGE
- Specify the type of elevation adjustment to be applied to the points.
- On
- Each point will be adjusted by the ratio of its offset distance from the match line to the maximum adjustment width, times the distance from the elevation of the point to its interpolated elevation to the other DTM layer. This method moves each point towards the other DTM. In the event the DTM layers cross in the overlap area, some points on each DTM may move up and others down. Generally this is the preferred method.
- Off
- Each point will be adjusted by the ratio of its offset distance from the match line to the maximum adjustment width, times the elevation from layer 1 to layer 2 on the match line perpendicular to the point being adjusted. This method moves each point based on the condition at the match line. If the DTM layers intersect in the overlap area, some points on each DTM may move away from the other DTM.
- MAX ADJ WIDTH
- Specify the maximum distance from the line in which points will be adjusted.
Tips on using DTMMATCH command
- The objects on the matched layers can be relayered to the same DTM layer for relinking.
- DTMMATCH makes significant modifications to the project data including deleting points. We strongly recommend that you keep a copy of the original data by using SAVEAS before you start.
- If DTMMATCH is to be used several times in one project file, save your work at each step.
- Before beginning DTMMATCH, you must have two DTM layers that overlap.
- Along the overlap create a single-segment pline or set where two DTMs are to match. Only points that fall within the length of the segment will be erased.
- Match lines should not be significantly longer than the limits of the DTM as this can prevent Terramodel from properly determining which points should be deleted.
- Set lines that cross the match line are clipped. A point will be created to hold each clipped set. The DTMs will re-link if required.
- Elevations of points that fall within the length of the line and the specified adjustment width will be adjusted according to the method specified. A set is created on each DTM along the match line through the points created. All points outside the match line for each DTM are deleted. The maximum elevation difference found along the match line, and the number of points adjusted, are reported.
| Command | DTM\DTM Match | S |
Create points by comparison with two DTMs.
Create new points on a third layer with elevations determined by a user-defined mathematical formula which may include the elevations of the first and second specified DTMs.

Create dynaviews.
Use a dynaview to display a portion of a view in another location.
For instance, you can create one dynaview around a part of the plan view, create a second dynaview around the same part in profile view, and combine these into a plan and profile sheet in sheet view. You can also create a enlarged view of a detailed area.
The advantage of a dynaview it that it is a dynamic view of the design, not just a copy. This saves memory, eliminates transposition errors and, when the design is updated, the dynaview is updated automatically.

Dynaview Options
- BOX
- Select the closed set or pline that defines the dynaview.
- LOC
- Enter the location of the origin for the new dynaview. The origin of a dynaview is the first vertex of the box pline.

- These real number controls let you enter factors which will be applied to calculated volumes to obtain excavation and fill quantities. Note: Generally, only the fill factor should be varied, leaving the excavation factor at 1.0.
- COMPUTATION METHOD
-
- VOLUMES TOTALS ONLY
- When the Volume Totals Only option is selected, only the total volumes will be reported.
- VOLUMES BY DEPTH INCREMENT
- When the Volumes by Depth Increment option is selected, the excavation/fill volumes calculations will be reported by a depth increment. When this setting is selected, you may enter the desired reporting interval in the real number control immediately to the right.
- VOLUMES BY ELEVATION RANGE
- When the Volumes by Elevation Range is selected, the excavation/fill volumes calculations will be reported by elevation range. When this setting is selected, you may enter the desired reporting interval in the real number control immediately to the right. Terramodel uses the value entered in the index elevation control as a basis for calculating the intervals. For example, if the interval is 2 metres, the index elevation is 100.5 metres, and the elevation range of the excavation/fill area is 98.5 to 106.5, the volumes are calculated for 98.5-100.5, 100.5-102.5, 102.5-104.5, 104.5-106.5, etc. As you can see in this example, Terramodel automatically finds the minimum and maximum elevations for the excavation/fill volume and reports the volumes over the entire elevation range.
- ISOPACH DATA CREATION
-
- SAVE COMPUTED ISOPACH
- When checked, the isopach surface will be stored on the selected layer. When not checked, the isopach surface is computed in the same manner and then automatically deleted.
- ISOPACH COLOURS
- Select the colours for points in areas of excavation, points in area of fill in the isopach, and breaklines.
- SURFACE TO SURFACE
- Compute and report cut and fill volumes between two DTM surfaces.
- SURFACE TO DATUM
- Compute and report cut and fill volumes between a DTM surface and a datum.
- STOCKPILE
- Compute and report the volume of a measured stockpile, based on an assumed underlying surface.
- DEPRESSION
- Compute and report the volume of a measured depression or excavation, based on an assumed original surface.
- ISOPACH
- Compute and report cut and fill volumes associated with a previously stored isopach surface.
Tips on using EARTHWORK command.
- DTM
- A Digital Terrain Model is also referred to as a Triangulated Irregular Network or TIN.
- Isopach
- The isopach surface is the surface representing the difference between two other surfaces. Isopachs are contours extracted from the isopach surface. CONTOUR or TVLITE the saved isopach surface to check for erroneous data in the other surfaces.
- Quick isopach generation
- For an accurate volume, make sure Quick isopach generation in LINKSET is OFF so that all the intersection points between the triangles are included in the isopach surface.
- Pond Volumes
- The volume of water displayed is the excavation volume rather than the fill volume.
- Initial Surface to Design Surface Volumes
- If your design surface has batters to an existing surface, project the batters using DESIGN or SIDESLOPE before calculating volumes to insure that the design sideslopes are projected. Otherwise, vertical sideslopes may be projected up or down.
- Surface to Surface Computation
- Surface-to-surface volumes are calculated by computing the isopach between two DTMs or between a datum and a DTM. First, each point is projected onto the other surface, the corresponding elevation interpolated, and the elevation difference is stored with the generated isopach point. The breaklines (of both surfaces are used to generate isopach breaklines. Additional points are inserted into the isopach breaklines where they cross DTM triangles.
- Computation
- The triangulated isopach surface is used to determine the volume by breaking the data for each triangle into the appropriate number of truncated vertical prisms. If the three points of a triangle all have positive or all have negative elevations (all fill or all cut) then a single triangular prism is present. If the isopach triangle has both positive and negative elevations (cut and fill) then the triangle is broken into a triangular prism and a quadrilateral prism. See Terramodel Help for this command for illustrations.
- The volume of each prism is equal to the average height (that is isopach elevation) times the planimetric area. The total fill volume for the isopach is the sum of all positive prismoidal volumes. The total cut volume is the sum of all negative prismoidal volumes.
- This method is more accurate than cross section or grid methods using average end area. The differences obtained between methods depend on the size of the grid or interval of cross sections and irregularity of the surfaces. Smooth surfaces may show differences of less than 1%. Some test cases have shown differences of as much as 10% when the cross section interval is 50 foot and the terrain is rough. As the size of the grid or cross section interval decreases to a very small value, the volumes of these methods agree with volumes computed from the isopach surface triangles.
- The accuracy of the calculations is no better than the accuracy of the data and the calculated DTM. If breaklines are not properly used to form the proper TIN, good point data can produce bad volumes. If an insufficient number of points are used to describe a surface, then irregularities from the recorded data to the actual ground will produce volumes differing from field conditions.
- Additional points
- To roughly estimate how many extra points you must allow for when setting the maximum number of points in Terramodel, using SYSTEM command, add the number of points in the two surfaces and multiply by two. Terramodel has a limit of 8 million points. Some of these points will be duplicate. A point is duplicate if it is on the same layer and is within 1 mm. Duplicate points are often created when computing the isopach surface, especially if a boundary line is used. Duplicate points are relayered to layer 0 during the linking process. These these points can then be deleted from layer 0 to save space.
- Special Case: Link setting "remove flat triangles"
- Normally triangles are created to be as equilateral (equal interior angles) as possible. The "remove flat triangles" setting in LINKSET changes the DTM to eliminate, as much as possible, flat areas. This technique is usually used on data from imported contours, forcing each triangle to have a slope. If the points along a set line are within a tolerance of the first point on the set line then flat triangles are removed. Adding and or removing break lines may be required to achieve the desired results. Note that "flat" lines in DXF and DWG files are automatically imported as plines, so you have to CONVERT to sets.
- DTM Edge
- Once you have the correct link settings for a DTM, use DTMEDGE to fix the boundary to with a bounding set. Then you can change link settings on another surface without effecting the first surface.

Modify the elevation of points along a set using a vertical angle
Modify the elevation of selected points within a particular set based on their position along the set with respect to a 3D reference point in that set, and a vertical angle.
If the specified vertical angle is other than a vertical distance, Terramodel multiplies the implied slope by the horizontal distance between the points along the set's alignment, and adds the resulting change in elevation to the elevation of the reference point to compute the elevation of the selected point.
- If *
- The selected point's elevation will always be set to the computed elevation.
- If <
- The point's elevation will only be altered if the computed elevation is less than the point's existing elevation, or if the point is currently a 2D point.
- If >
- The point's elevation will only be altered if the computed elevation is greater than the point's existing elevation, or if the point is currently a 2D point.
This command is similar to ELEVREFPT, except that the distance between the selected point and the reference point is determined along the horizontal alignment of a set within which they are both members.
See also ELEVREFPLANE.

Modify the elevation of points along a set using a vertical angle
Modify the elevation of selected points by projecting them vertically to an imaginary plane surface.
The plane surface is defined with respect to a 3D reference point by specifying a bearing, and a vertical angle.
The vertical angle is applied in the direction of the indicated bearing, establishing the tilt of the plane surface, which passes through the reference point.
- If *
- The selected point's elevation will always be set to the computed elevation.
- If <
- The point's elevation will only be altered if the computed elevation is less than the point's existing elevation, or if the point is currently a 2D point.
- If >
- The point's elevation will only be altered if the computed elevation is greater than the point's existing elevation, or if the point is currently a 2D point.
See also ELEVREFPT.
| Command | Modify\Elevation\Reference plane | S |
Modify the elevation of points along a set using a vertical angle
Modify the elevation of selected points based on their horizontal distance from a 3D reference point and a vertical angle relationship.
If the specified vertical angle is other than a vertical distance, the implied slope will be multiplied by the distance between the points, and the resulting change in elevation will be added to the elevation of the reference point to compute the elevation of the selected point.
If the specified vertical angle is entered as a vertical distance, it will simply be added to the elevation of the reference point to get the elevation of the selected points.
- If *
- The selected point's elevation will always be set to the computed elevation.
- If <
- The point's elevation will only be altered if the computed elevation is less than the point's existing elevation, or if the point is currently a 2D point.
- If >
- The point's elevation will only be altered if the computed elevation is greater than the point's existing elevation, or if the point is currently a 2D point.

Explode blocks, text and complex linetypes
Explode selected blocks into component parts, and text and complex linetypes into plines.
Optionally, delete the old objects.
The exploded components are created on the current layer only. Use GCEXPLOD instead to explode to the same layer as the block while and retain the elevations and names.
Blocks are exploded into the component plines, text and blocks. Because blocks can be nested inside blocks, you may need to explode more blocks.
Text containing EAT codes is exploded into ordinary text. Ordinary text is exploded into plines. Text linked to points, such as dimensions, loses those links.
Sets and plines with complex linetypes are exploded into plines and symbol text. Solid lines are unaffected. If you want to separate a line into segments, use DISJOIN instead.
To select or restrict by Type, such as blocks but not text, use SEARCH settings or Right mouse button Type.

Filter vertices in plines.
Replace selected plines with plines made up of straight segments within a filter "box". This will usually reduce the number of vertices for plines containing straights, such as contours, and increase the vertices for splines, arcs and spirals.
The initial filter box is of the specified length and orientated to the first segment on the pline with width perpendicular to the segment.
FILTER checks for additional vertices that are contained within the limits of the filter box. Any vertices inside the box are discarded. The first vertex found outside the box is kept, and the last discarded vertex inside the box is added back to the pline. The tube is then reoriented based on the last two vertices, and the process is repeated.

Toggle elevations.
Label points with elevations. Run F9 again to turn elevations off.
Replace any point labels placed by F7 or F11 with different predefined point labels so that the only the elevations toggle and the visibility of the point number and name labels is unchanged.
Point symbols, blocks and other point labels are unchanged.
The size is dependent on the current view scale at time of creation. To change the size, change the view scale with VIEWSET or VIEWSCAL then toggle off then on.
The colour of the label is the same as the point colour.
F9 command is assigned to F9 function key by the Geocomp Update. Alternatively, use an ALIAS or a toolbox button.
The point labels are the same as those placed by LABELPOINT. These labels are intended for quick use while editing your data. If you are drafting, use LABPT, BLOCK or AUTODRAFT instead for control over colours, size, layers and so on.

Create mid-points on short plines.
Where a two-point pline is less than a minimum length, create a mid-point.
If the mid-point of the next pline is in the same location, the duplicate point is omitted.
A common use is to create a single point on each pair of crossing plines imported from CAD.

Helmert transformation.
Using pairs of points, compute a best fit of shift, rotation and scale then transform the selected data.
- Objects
- Select the objects to be transformed
- Use Form
- Enter up to nine control point/data point pairs into the form by point number or mouse. Give each a weighting of the number of times each pair is to be used. Then Calculate the Rotation, Scale, East Shift and North Shift for each pair. If the reported residuals are acceptable, click Transform Objects. If you will need to make the same transformation with different objects, store the Transformation Values as project variables or to a .HMT file.
- Use Stored Values
- Selectable if transformation values have been stored as project variables using the form.
- Use Stored Values from file
- Use a .HMT file stored using the form.
- Read Control/Data points from a file
- Read point pairs and weights from a .csv file. Use this when you have more than nine point pairs, or they are supplied in a table. The file format is either Control_Point_number,Data_Point_Number or Control_Point_number,Data_Point_Number,Weight.
- Transform Points
- Transform point pairs defined by stored values or CSV file.
The HMT file contains three pairs of parameters on one line. The first two combine to store rotation and scale, the second locates the data centroid and the third, locates the control centroid. If a HMT file contains two lines, the first line is a heading displayed in the message scroll and the second line contains the parameters.
See also GC38 for Affine transformation, which uses different scale factors in North and East, and GC3DROT, GC3DADJfor 3D transformation.
If shifting, rotating or scaling around a single point, use MOVE, SCALE, ROTATE or RTSCALE.

Places blocks or symbols by group.
A mapping file (default = Geocomp.map) determines the block or symbol, the size and scaling behaviour. If the group =0, no symbol is placed.
Most import TMLs written by Geocomp Systems set a group for each object. If you import or create objects in other ways you will need to assign groups to use this function.
GCIMPORT enables this method during the import by selecting "Map Points and Circles with Blocks or Symbols". To place the blocks or symbols at a later stage, use GC09 after setting groups where required.
To replace circles with blocks by group (for example tree canopies), use GCIMPORT or GCINSBLK.

Import 12D ASCII file.
Import 2D, 3D, arc, text and alignment strings from .12DA file.
You can specify a user-defined comma-separated mapping files for colour, layer name and line styles.
If you leave a mapping file field blank, will prompt you to create one with suggested values for records found in the 12DA file. Colour mapping files with extension .CNN are in the format in the format 12DA colour name, Terramodel colour number.
The layer name mapping file with extension .LNM is in the format 12DA model name, Terramodel layer number. Terramodel uses the first matching case in the file. If you select an .LNM file, any new model names in the .12DA file are added to the end of the file.
The line style mapping file with extension .LSM in the format 12DA line style name, Terramodel line type name. Terramodel uses the first matching case in the file. If you select an .LSM file, any new line styles in the .12DA file are added to the end of the file.
Horizontal, vertical and slope alignments from super alignment strings are imported as plines and registered.
