I've hacked together a Macro that will save an open drawing as PDF and DXF.  Now I want to have it open the model from the drawing and save it as a STEP file.  I can't figure out how to use the link between the drawing and the part to open the model from the drawing.

The drawing and model will always be in the same folder, but not necessarily with the same exact name.  To be sure that the part file used is the current referenced document, I would like to open it from the already open drawing.

Any ideas?
