Convert SLDASM to STEP

QUICK ANSWER
Is it possible to convert SLDASM to STEP?
Yes - SLDASM converts to STEP.

The best neutral exchange format - STEP (.step/.stp) is read by virtually every CAD program (Fusion 360, Inventor, FreeCAD, Onshape). In SOLIDWORKS: File > Save As > STEP. Exports the whole assembly's solid geometry as one model (the editable mates/history do not transfer).
