Convert VDAFS file to DXF file (in 3DFACE entities) and generates a NC program for milling by some paths parallel to the machine axis. 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. You can load STL ascii files generates by AutoCAD for solids and you can calculate the volume and center of gravity of some bodies limited by 3DFACE entities. RCAD 2.0 graphic core, distributed together with VDAFS TO DXF&NC Converter & Viewer, provides OpenGL real-time orbit, pan, zoom, shading and lighting.
