Hi Igor - in those screen shots you mention things like "This is an imported SAT file..." - it would be a big help if you could include all those related files instead of only a screenshot. Like if you have some example about a particular SAT file, please post the SAT file (and any original .3DM file as well) so I can try to examine the model data.

It is hard for me to tell specific things like details about the surface definition and topology just by looking at a screenshot.

Thanks,
- Michael
