GeoMESH is an additional application for Autodesk® AutoCAD® (ObjectARX App) for creating and editing digital elevation models (DEM) and triangulated irregular networks (TIN). GeoMESH provides commands for 

  • Reading terrain points from LAS- and Text-Files,
  • Generating terrain models for irregularly distributed terrain points (constrained delaunay triangulation),
  • Generating contour lines,
  • Generating colored contour line patterns,
  • Constructing terrain sections,
  • Applying ortho images onto terrain models,
  • Calculating volume differences between different terrain models. 


GeoMESH is not meant to be a competitor product for much more complex and expensive software packages, but a compact and targeted solution for modeling digital elevation models (DEM) and triangulated irregular networks (TIN).

GeoMESH is seamlessly integrated into AutoCAD via its commands and thus offers a user consistent usability. 

GeoMESH reads and generates standard AutoCAD elements so that further processing of generated data and geometries with AutoCAD itself or other software solutions is possible at any time. GeoMESH is therefore an open system that offers maximum freedom.

The trial version of GeoMESH 2.4.0 provides full functionality with a limitation of 100 terrain points. Have fun!


版本 2.4.1, 2024/5/30
- Optimized mesh algorithm (command GMESH), using part on CDT (C++ library for Constrained Delaunay Triangulation, Copyright © 2019 Leica Geosystems Technology AB, Copyright © The CDT Contributors, Licensed under the MPL-2.0 license, ''). - New command GMSETVAR to access all GeoMESH system variables. Works like AutoCAD command SETVAR. Direct access typing GMSET+"variable name" still possible. - Removed GeoMESH command GMHELP. Please use this website for help information about GeoMESH. - Removed GeoMESH system variable CALCMODE or GMSETCALCMODE. Only one fast and optimized mesh algorithm now available. - Removed GeoMESH system variable MAXDATA or GMSETMAXDATA. New general data limit is 10e7 terrain points, in Trial-mode 100 terrain points. - Removed GeoMESH system variable GROUPMODE or GMSETGROUPMODE. Use AutoCAD system variable PICKSTYLE instead. GeoMESH creates now always groups. - Removed GeoMESH system variable UCSMODE or GMSETUCSMODE. GeoMESH uses now always the current UCS. - Modified GeoMESH system variable CINCR or GMSETCINCR. No more negative values allowed. - Modified GeoMESH system variable VOLPREC or GMSETVOLPREC. No more negative values allowed. Use instead the new GeoMESH system variable VOLDRAW. - New GeoMESH system variable VOLDRAW or GMSETVOLDRAW. Switch for rendering volume bodies using the GMVOLUME command. - Bug fixes.
