Yep, thanks. I did some more messing around with TC and MOI last night to move the STL into MOI and got it to work. The problem that I was having was a lack of patience. With the IGES files that TC created, it took MOI over an hour to import it into the drawing. It didn't seem like a big model but it turns out to be pretty large, created a 40M MOI file as a result. Not sur if it is size or lack of processor power that makes it take so long, probably both.

If any one knows a way to speed it up........ Otherwise I can just learn to live with it.

Thanks
