Digital Terrain Modeling

Digital Terrain Modeling runs inside AutoCADŽ or IntelliCADŽ based CAD systems, giving you time saving contouring and profiling commands right inside your favorite CAD package!

Digital Terrain Modeling provides an economic solution for surface modeling and is suitable for use on subdivisions and other areas where you need to show existing or proposed ground profiles, existing or proposed ground contours or where you need to get volumes between two surfaces.

Any point file in the xyz format can be used to create a surface model. Objects may be selected from the screen. Fault lines may be added to the model to control the triangulation process. Boundaries and voids may also be used to control the appearance of the model.

Create a TIN (triangulated irregular network) of a set of points.

Set elevation limits on the surface model.

Contours may be created at user defined intervals.

Contours may be placed on user defined layers in the drawing.

A mesh may be created of the surface.

Volume calculations may be made between two surfaces.

Create an unlimited number of surfaces.

Import surfaces from a LandXML file or export surfaces to a LandXML file.

DTM Profile Cutter


Select a polyline alignment and cut a profile from the surface. The profile may then be imported into a drawing. The program places a grid around the profile and annotates stations and existing ground elevations on a user defined interval. You may overlay the existing profile with a new profile cut from a modified surface model.
