Does anybody here have experience using Alibre stl or iges 3d files for VM? If so what file type do you use and what settings are required for proper file export from Alibre to keep VM happy? I find that some corner radius es are exported in several sections and VM wants to put lead in and lead outs on every section, so for a simple "u" shaped cut out rather than having one lead-in and one lead-out, it has several all through the "U" shape cut out. I suppose one could machine each section of the radius seperatly removing the leads but that would be a pain. Any thoughts? I really like using Alibre.........but if the two are not compatible then I should stop while I am ahead.
