Why can't I read my Iges geometry file into Ansys Classic with the IGESIN command?


Check the Import Summary, and if you see the word "UNSUPPORTED", the Iges file contains surface entities that cannot be translated by the IGESIN Command.
See example below.

In particular, the Ansys Classic IGESIN command only supports the Iges "Trimmed Surface" entity. It does not support nurb or other b-rep surfaces. The work around is to have your CAD system export a new iges file using the Trimmed Surface entities.
