Pad script recalculate Z height into non metric distance about kicad-footprint-generator HOT 6 CLOSED

I found the reason

If you create the 3D model like this

f.append(Model(filename="${{KISYS3DMOD}}/Valve.3dshapes/{}.wrl".format(s), at=(0, 0, socket_H)))

The result in the .kicad_mod file is

  (model ${KISYS3DMOD}/Valve.3dshapes/Valve_Socket_Belton_VT9_PT-B9A-D21.00mm_Tap.wrl
    (at (xyz 0 0 3.5))
    (scale (xyz 1 1 1))
    (rotate (xyz 0 0 0))

but kicad itself will scale up 3.5 with 25.4 so the z position will become 88.9000 when 3D-viewing the foot print in the foot print editor.

If you change it back to 3.5 and save the foot print, kicad change it to this

  (model ${KISYS3DMOD}/Valve.3dshapes/Valve_Socket_Belton_VT9_PT-B9A-D21.00mm_Tap.wrl
    (offset (xyz 0 0 3.5))
    (scale (xyz 1 1 1))
    (rotate (xyz 0 0 0))

so apparently kicad re scale distance if you use (at (xyz 0 0 3.5)) but not if yo use (offset (xyz 0 0 3.5)) this is clearly some mistake in kicad.

Also

There is a serializer function in Model.py but that is not used becaouse KicadFileHandler.py is ignoring this function and use it's own, def _serialize_Model(self, node): at line 149

So, it is not possible to modify Model.py to handle both at and offset arguments to Model.py

from kicad-footprint-generator.

With the valve push I will include a fix both in KicadFileHandler.py and Model.py so it will handle both at and offset where at supersede offset

Closing, see push
KiCad/kicad-footprints#1111

from kicad-footprint-generator.

When I create a new footprint just for testing and add a 3D model in v5 I see this:

  (model ${KISYS3DMOD}/Button_Switch_SMD.3dshapes/SW_DIP_x10_W6.15mm_Slide_Omron_A6H.wrl
    (at (xyz 0 0 0))
    (scale (xyz 1 1 1))
    (rotate (xyz 0 0 0))
  )

For what it's worth, I think the wording has changed and offset is no longer used.

from kicad-footprint-generator.

I can not use 'at' for the valve socket + valve (2 3D models in one foot print)

If 'at' is used, then kicad automatically will multiply with 25.4 first time (and convert it into an offset and save it like that)

But the 'offset' is not recalculated but stays as it should be and the second 3D model is placed in the correct place
