Is useful in topography for representing and editing 3D points (by 3DPOLY, SPLINE OR BLOCK entities) and for triangulation, isolines, cross sections and longitudinal profile. It exists a modifiable library for codes and BLOCKs. The coordinates, the code and the position (in 3DPOLY or SPLINE) of the points can be modified interactively. You can load STL ascii files generates by AutoCAD for solids and you can calculates the volume and center of gravity of some bodies limited by 3DFACE entities. RCAD 1.7 core provides OpenGL real-time orbit, pan, zoom, shading and lighting.
Requirements: Graphic card with OpenGL hardware acceleration and 32-bit color depth, Windows XP and computer admin
