TerrainCAD for Rhino - Terrain modeling plug-in for Rhinoceros

TerrainCAD for Rhino is a terrain modeling plug-in for Rhinoceros. 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.

IMPORTANT! Purchasing a Subscription is highly recommended since it the most cost effective way of keeping your software up to date. Moreover, Subscription entitles you to get a second free perpetual license for your laptop, among many other benefits. For details please read the SYCODE License and Subscription Frequently Asked Questions (FAQ).

Our licenses are single computer licenses and are locked to each computer they are installed on. Basically, the license key is specific to the computer's Host ID (the MAC address of the computer), and will not work on another computer. The installer picks up the physical MAC address of the network card connected to the computer which is basically “Ethernet adapter Network Connect Adapter”. So unless you change your network card, the key will always work even if you reinstall your operating system. If your internal network is periodically assigning a different Host ID to your computer, then please find a solution for this with your IT department.
