Hi pafurijaz,

Thanks for your feedback!!

Just for info, I exported the solid called "Platte m Nut u Loecher" by selecting just this solid before exporting. So the other elements are not exported and also not visible in the IGES file. Attached in my initial message the 3dm file and the 2 versions of the IGES files.

So actually I still have the issue.

Best regards,
