Im Pretty new to CNC, but Ive been using Lightwave3D for about seven years, and as much as i'd like to get into CNC, Lightwave is still how I pay the rent.
My Mastercam experience is limited to school. Now, I realise that most of the time a CAD program is the way to go, BUT- for complex organic shapes Lightwave really is better. Each is of cource better for what it was made for.
Ive seen some things (including some threads here) that deal with convertiong between the two, but only to get wireframes, usefull only for parts best drawn in a CAD program in the first place. Converting a Nurbs model to thousands of tiny polys is fine, but its the toolpaths that are then a problem. What i really need is a way to A) 'drape' a grid of cuts across a wireframe instead of following the mesh or B) get surfaces to convert so i can use regular surface toolpath tools in Mastercam. Maybe there is something in Mastercam you know of that does A? seems like it would be a standard toolpath type but it doesn't look like it has it so far. If not, maybe there is a converter i don't know about to go the other route(B)? I have tried Polytrans and "3D Object Converter 3.1". they even support IGES but you still only get wireframe with no surfaces where the polys were. Any ideas at all would be great, because I can't seem to get this to work at all. Thanks for looking at this thread!
