You could possibly use the virtual flag for 3D model only footprint but I've never tried it so it may not work. If it's possible, then I see no reason not to allow it although it does seem like a bit of a convoluted solution that may confuse users. Creating a footprint with no pads, silkscreens, and/or text and only a 3D model seems a bit counter-intuitive to me. > Please note that if you use e.g. a mechanical TH pad, the pad footprint > will be displayed in 3d-viewer also if Virtual, but the 3D model will or > will not in function of the virtual flag > >> It is not missing, it is not yet implemented in my branch :) .. the >> options is still there in same place. > ok, I just will wait/hope for the resurrection :) > >>> it is a personal local branch... >> Is it online?
