Hi there,

currently the step models created by FPX consist of many different sub-parts, e. g. a sub-part for every pin and the body.

So the step model of a PCBA with a lot of components has A LOT of sub-parts. Unfortunately our mechanical CAD tool (Creo) appears to have problems with step models that have a lot of sub-parts.

Would it be possible for FPX - maybe optionally with a checkbox - to create step models as a single part? This would significantly reduce the number of sub-parts in the step model of a PCBA.

As a single part it should still be possible to have pins and body in a different color, for example.

Our Solidworks chokes often on PCB STEP model with too many complex component STEP models.
If you are using Orcad or Allegro, there is a factor making the STEP model bigger than they should be and more tedious to load into a CAD tool. I discovered that Footprint expert is using the old Orcad 3D mapper to map a STEP into a footprint. I do not know why but it results in a larger footprint file. Instead of using Footprint expert batch file, if I manually map the STEP model using Orcad 3D canva, I obtain a subtantialy smaller footprint file, especially for BGA with hundreds of pins. It is easier for Solidwork to load the resulting PCB step model. However for large PCBs, I still have to delete complex components before exporting the 3D PCB model otherwise Solidworks will choke.
So anything to make the STEP models smaller is very welcome.
