Thanks Michael,

I'm not too concerned with that, as a mesh to a simple solid is fine with me. I have things like Star Trek saucers (geek alert) in stl and obj formats that I'd like to import into Alibre and MOI and manipulate but can't. Losing parametric data on a 1/1000th scale Trek model, for example, isn't too concerning as long as the converted file results in something that I can then work from, build off of, and so on. Does that make sense?
