3D models of PCB

Having 3D model is crucial for checking before production.

Best way to do it is to convert PCB to KiCad, add missing 3D parts and export to STEP.

If needed models can be exported to format known to blender (VRML).

Blender would be better for some rendering/animation purpose, but for checking dimensions we can use freecad.

Always export 3D model in default directory it will use parts from same directory so if you export to some other directory parts will not show up on your board.

First we need to convert board to KiCad.

That is done by opening KiCad and select Import -> EAGLE CAD

After conversion we just need to open PCB file

PCB will show, but without

We need to start DRC

And select yes for refill polygons

Next double click on each part that is missing 3D model and select appropriate model, you can find models installed by KiCad or on manufacturer webpage. You can also check snapeda.

Test on KiCad Render by selecting 3D view

When all is done you can export STEP file

And import into freecad

Do same for each module and import them all in freecad
