not sure if it is MOI’s issue but the step import has filled faces with the follow area while in ALIAS it is as it should be.[image][image]

I am pretty sure it is MOI. One of the strongest capabilites of OCCT (the underlying modeling kernel in Shapr) is data exchange. I never had any problem with STEP export with any other modeling app.

LOL I smell Rhino math issues …

I imported some STEP files into MODO with the Power Translator and they were all fine. Maybe some MOI issue?
