TRIANGULATION performs triangulation of a set of 3D points width compulsory interconnections. ISOLINES determines the curves of intersection of a set of 3DFACE entities width a set of plane equidistances horizontally or vertically. VOLUME determines volume and center of gravity of a body limited by 3DMESH and 3DFACE entities. 3DINTERSECTION determines the intersection curves between 2 sets consisting of 3DFACE or 3DMESH entities.

Convert VDAFS file to DXF file (in 3DFACE entities) and display the result. RCAD 1.4 core provides OpenGL real-time shading and lighting. There will be interpreted the entities of type PSET, FACE (created from the entities of type SURF and CONS) and possibly those of type SURF.

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. RCAD 1.4 core provides OpenGL real-time shading and lighting.
