I have a problem... I want to use OpenCASCADE in two different ways. Firstly to simply visualize motions of parts of a machine tool structure and secondly to calculate overlapping volumes between parts. This calculation cannot be done with boolean operations because I have to simulate a tool path through a workpiece, and lots of such operations have to be made during the simulation.
The 3D Data of the machine tool parts is given in STL-format and there is no way for me to get IGES or STEP representations of these parts which could be read in easyly with OpenCASCADE. So how can I import STL? Can you give me an example on how to do the import usig the OCC primitives and which works fastly. Or is there any library available which does the job?
