I got a project that has one main board, and 6 breakout boards that are mounted with pin headers.
Is it possible somehow, to visualize the breakout boards on top of the main board in pcbnew, or, even better, visualize it in 3D ?
You will want to look at importing your boards and parts models into freecad. Once in freecad you can manipulate your boards and assemble them in 3d.
please have a look at:
All right, cool. I'll definitely try that !
