I am trying to write a macro such that when in a drawing it will save the drawing as a PDF and a DXF file. Then it will get the referenced part and save that as a STEP and IGS file. Saving as a PDF, DXF, and STEP all work as intended, but my macro doesn’t work when it gets to IGS. Attached is the macro. Is there something that I need to do differently when saving as IGS?
