No idea about AutoCAD. SW - I used it to create complete 3D model of fitness equipment approximately of high end treadmill complexity. The resulting model went to 2 factories to produce all the parts (except fasteners obviously). Haven't had single crash but of course I can bet that I did not use all the functionality. So maybe there are parts of SW that are less "stellar" but I did not encounter those.
