Using KiCAD 5.0.1 on Windows 10. I have a step file with the 3D shape I want.
I also have an SMD footprint that I created. In the footprint editor, I went to Footprint Properties, the 3D Settings tab, removed all 3D shapes, and added the step file. In the add dialog, the shape looks okay. But after I added it, the preview still shows the original default SMD footprint.
Still in the footprint editor, when I View > 3D Viewer, it just shows the default SMD footprint, and not my shape.
How do I get KiCAD to use my shape instead of the default?
