TerrainCAD for Rhino

TerrainCAD for Rhino is a terrain modeling plug-in for Rhinoceros® 3.0 and 4.0. This plug-in gives Rhino the ability to create a terrain mesh from a set of unordered points, lines and polylines. The terrain mesh is created as a Delaunay Triangulation, which is regarded as the best method to create a terrain mesh from unorganized point data. TerrainCAD for Rhino is powered by TerrainLib, a state of the art terrain modeling library developed by SYCODE.
TerrainCAD for Rhino is very easy to use. Once installed, it automatically loads itself into Rhino and adds a new submenu called "TerrainCAD" to the Rhino menu.
The 'TerrainCAD' menu consists of the following commands:
TCImportPoints - Imports points from a text file.
TCCreateTerrain - Create a mesh from a set of unordered points, lines and polylines.
TCHelp - Displays the TerrainCAD for Rhino help file.
TCRegister - Registers your copy of TerrainCAD for Rhino.
TCAbout - Displays the TerrainCAD for Rhino about box.
