ProDesktop Express has also problems with the file. Are you sure the IGES file is ok?

Dear Patrik,

The problem.igs face is read correctly.
But this face is not planar. So you can not create an offset at this face.

The Open CASCADE help say:

BRepOffsetAPI_MakeOffset Class
Purpose
Describes algorithms for offsetting wires from a set of wires contained in a planar face.
