Hi kmccall, for the STEP problem is it possible for you to send me the STEP file at moi@moi3d.com so I can take a look at what's going on?

For SAT format the problem there is probably the version of the SAT file, see if there are any options for the FormZ export to use an older SAT version like ACIS v8. That should then convert any specialized surface objects into generic NURBS surfaces which the MoI SAT importer will be able to recognize.
