Freeware application for digital terrain modelling (DTM) in AutoCAD.

CADstudio DTM is a freeware application for 3D terrain modelling in plain AutoCAD. You can use it for visualizations and simple terrain calculations and analysis.

The application is based on a TIN generator by D.Piazza and contains enhancements and functions from the CADstudio's application GEOsurf.

DTM allows to generate triangular terrain model (3DFaces) from any 3D points (objects) or contours in your DWG file. With this model you can then perform other operations - e.g. calculate volumes (above/below a reference plane), estimate point elevations on the model, generate flowlines. You can also use a generator of random 3D terrains.

(For advanced terrain modelling functionality we recommend to upgrade to AutoCAD Civil 3D.)

You can download the "DTM" application from Download (see the Readme).
