I have a temporary IGES file that I aligned in an assembly and gave it a new coordinate system that matches the assembly. I exported the file as an IGES again using the new coordinate system and imported it into an individual part. When I do so, some of the curves import based on the new coordinate system, but the 3D sketches and other curves still import with the original coordinates. Is this normal? Others here have seen the same behaviour and have various work arounds, but it seems like this should be basic functionality. Maybe there is a setting that I am missing?
