I used the "create swept volume" instruction to show the mig torch welding along the part. This instruction creates a "user defined resource" that shows the mig torch path in a 3D shape. Great! 

I would like to export this shape so our designers can use it to check for interferences when creating the tooling for the station. I exported this file as an IGES3D, STEP and 3DXML. When I open any of these files in solidworks, I am staring at a blank screen. There is no 3D shape.

Any Ideas on What I'm missing?
