I’m using the attached macro to generate DXFs from a multibody part in SolidWorks. It saves each DXF with a specific naming format that pulls info from both the part's custom properties and the cut list.

The DXF filename ends up looking like:
MK1-10382-010-01_5MM_MSPL_1OFF.DXF
That’s made up of: Project No + Number (from the custom properties) and THICKNESS + MATERIAL + QTY (from the cut list properties
