Basics of the Digital Terrain Model module

Function

Use

Terrain Point

You can use this tool to create points with point symbols (2D oder 3D), primary and secondary point numbers as well as stations and point coding.

Mesh, Optimize Grid

You can use this tool to create a new digital terrain model or optimize an existing one.

Contour Line

You can use this tool to draw contour lines in a DTM.

Elevation Point

You can use this tool to place elevation points in a DTM.

Profile Section

You can use this tool to place a profile through a terrain using orthogonal, inclined and freeform section lines, and to modify an existing profile section. Each profile is assigned to one DTM.

Import, Export Point File

You can use this tool to import point files and location line files in a variety of formats or export points and coordinates to a file. The files are exported to and imported from the user's data exchange folder.

Convert DTM Elements to 3D

You can use this tool to convert DTM elements to a surface model or solid.

Convert 3D Entities to DTM

You can use this tool to convert 3D entities to a DTM element.

Convert DTM Elements to 2D

You can use this tool to convert DTM elements to 2D.

Label Triangles, Contours, Points

You can use this function to label the triangles, contours and points in a DTM.

DTM - Color

You can use this tool to apply different shades of color to the various height levels in a DTM.

Activate Profile Section

You can use this tool to create a profile section based on existing profiles.

Compute Cut and Fill

You can use this tool to calculate the cut and fill according to REB. The cut and fill is calculated either by comparing two DTMs, or by comparing a DTM with the height of a horizon plane.

Use

Modify Terrain Point

You can use this tool to modify the parameters of terrain points.

Modify DTM

You can use this function to change the smoothing factor, the type of labels used for grid points, the location of contour labeling, and the number of decimal places in contour labels. The defaults for these values are set in the Options and can be modified for single DTMs using this tool.

In addition, you can control how textures are displayed in animation.

Grid Point

You can use this tool to add new grid points, change the position and height of grid points and delete grid points.

Mesh Element with DTM

You can use this tool to mesh an element’s control points - or the points where it intersects with existing grid lines - with a DTM.

Exterior Boundary

You can use this tool to create, modify and delete an exterior boundary of a DTM. The exterior boundary defines the area of a DTM within which Allplan will perform calculations, apply labeling and update data automatically.

Cutaway

You can use this tool to insert cutaways in a DTM. Contour lines, elevation points and labels are not displayed within these regions.

Breakline

You can use this tool to define terrain edges. Triangles with these mandatory grid lines are not optimized and calculated as breaklines.

Representation

You can use this tool to specify which DTM elements are displayed on-screen.

Freeform Slope

You can use this tool to create freeform slopes between two elements (slope area and slope edge). The slope ratio is calculated automatically.

Slope

You can use this function to draw slopes by entering the outline of the area to slope, or the edge of the slope and then its angle. You can define sloping areas with different angles of inclination.

Raise 3D Elements

You can use this tool to raise 3D solids to the height of the terrain.

Move DTM Text

You can use this tool to move the labels (triangle labels, contour line labels and grid / elevation points labels) in a DTM.

Unlink DTM

You can use this tool to unlink a DTM. This will delete the entire model so that only the original grid points are left.

Delete Label

You can use this tool to delete the labels (triangle labels, contour line labels and grid / elevation points labels) in a DTM.

Delete incl. Contours and Elevation Points

You can use this tool to delete elements including contour lines and elevation points.
