I am a long time Mastercam user. We build plastic injection molds. This is an extremely competitive field and we are constantly looking to become more competitive. We have a Topsolid demo scheduled for this thursday am. This product appears far and away superior to Mcam according to current users that I know, most using Mastercam until buying this software. Anyone familiar with this product and know the strengths/weaknesses of it? I will post more info after the demo.
