Hey,
I am trying to program a 3D contour with inventorCAM and I'm starting to pull my hair out, one each 3 seconds :) The auto curve propagation is so damn slow! Look at the video below. Is there another approach to my situation? Or another CAM software out there that is able to work with 3D drawings (not solids)? The perfect solution would be to be able to automatically select all curves that intersect the triangular solids.
