fyi to anyone seeing cg, inertias, mass etc...

looks like the low cost version of Atom3D will do this. however, you have to buy the expensive version of TurboCAD to do the same. I couldn't find any information for TurboCAD. I had to get in touch with them. So not really even sure how good it would do this task. There are videos for Atom3D / Alibre. Which show that it does the task well.
