It's "OK" but for us to convert to parametric would be a major PITA. We use too much legacy stuff for new projects. We would have to re-invent out entire library (over 6000 parts drawn in 3D) and start from scratch on all ensuing projects. I'm gettin too old for that s**t. Right now I've got a very good system for 3D modeling in vanilla CAD....if it works, don't fix it............
