I'm new to assembly appearances. For assemblies where all parts are spray painted, it's easy. Just highlight the assembly and color it. For other assemblies, we mask a few faces so they do not get painted. There other dozens of surfaces that get painted, so picking every face to paint would be very time consuming. Is there a way to color the whole assembly and then remove the handful of faces? Or select all faces, deselect a handful, and then color them?
FYI, I am on a Covid19 furlough Sunday 21 thru Sunday 28.
