Hi Bob, maybe Geomagic is applying some scaling factor to your object and that's why there are different results.

That's just a guess though - if you could post the 2 STL files you are talking about - the one from MoI that you're having problems with and the one from Geomagic that works better, I might be able to look at them and potentially find out what the differences are between them.

If you want to keep them private you can send the links to me directly at moi@moi3d.com, you will probably need to use a file sharing service like Dropbox or Microsoft OneDrive to host the files if they are fairly large, then just send a link instead of trying to send the entire large file directly.
