I have designed a 3D shape for a photo-darlington OP580DA.
I designed parts separately so I can include colors where is needed since I am using FreeCAD 0.17, I have combine all parts together using Assemby2 WB I export it as a STEP file.
when I align the footprint with 3D shape using Kicad StepUp WB its get difficult because I can’t move the hole 3D shape only parts as I designed them.
My question is,
which technique to use in designing a custom 3D shape with colors using FreeCAD (because it is the one recommended for KiCAD 3D shapes)?
Which way is used by librarians to make their own 3D shapes?
