The attached .skp file contains one group composed of elementary items (lines, surfaces). The group item is in layer “old door”. All its lines and surfaces are in Layer 0. I cannot remove layer “door”: it supposedly contains something. Eneroth Layer Usage Inspector says layer “door” is used by the group item. How?
All surfaces in the group item are painted the default color. Yet I cannot remove two in-model textures via Purge Unused. Why?
I must be missing something, but I have no idea what.
