But when I try to view the model in 3D Viewer in Assign Footprints or in Pcbnew, I only see the silkscreen on the PCB. In 3D Viewer all the 3D Model Visibility options are checked off.
If I check Preferences / Manage Footprint Libraries, I can see that KISYS3DMOD is set to /Library/Application Support/kicad/modules/packages3d, which I guess it should be.
Try: Edit a footprint, edit 3D shapes, can you see in the dialog the option to choose file formats extention of WRL and STEP ? If you can’t choose that file extensions then something is wrong with the installation, probably an issue from where you get the installation package. i.e: the 3D plugins are not placed or pointed to the correct path.
Yes! Thank you. After I deleted all symbol libraries in Eeschema and added symbol libraries from /Library/Application\ Support/kicad/library/, and deleted all footprint libraries in Pcbnew and added footprint libraries from /Library/Application\ Support/kicad/modules/, the 3D models show up.
