This is my clue to reiterate my proposal to not touch STEP at all but 
communicate the 3D geometry to freecad. Freecad supports python commands 
as a 3D geometry description. This essentially a scripted geometry 
definition.

The freecad developers have managed to successfully export STEP data of 
their models since a number of years. The application is able to run GUI-
less and can do whatever you please via python scripting. If pcb can 
export to freecad, the road to valid STEP data is free (pun intended :-)
