FreeCAD 3D Model Auto-Alignment

[topherbuckley]

Anyone know how to use FreeCAD to auto-align the pins to the holes/pads? It doesn't seem the is any particular fixed offset/rotation that I can hard code in so wondered if there was any auto-align tools out there. Not sure how that'd work, but thought I'd at least ask.

Hi even if it does not answer your question. In some libraries, even the needed rotation and translation is included. But it is ignored in your lib.

Sorry, I haven't touched this is quite a while. Can you reference an example where such rotation and translation is included and where it is ignored in the lib?

  (model 744043151.stp
    (at (xyz 0 0 0))
    (scale (xyz 1 1 1))
    (rotate (xyz -90 0 -90))
  )

  (model XPGDWT-N1-0000-00XPP.stp
    (at (xyz 0 0 0))
    (scale (xyz 1 1 1))
    (rotate (xyz -90 0 0))
  )

Thanks! I think I see your point. Offset, scale and rotate are all currently hardcoded in a string rather than extracted from the kicad_mod file. Happy to merge a PR if you wanted to fix this. I won't have time for a while to pick this back up and am not recalling off the top of my head how the parsing was working.

I have added this to my repository. I hope it is recognizable which change the feature realizes.
