How do I remove a material?
I created a new exterior wall sheathing and posted it in the wrong area. I found that I could remove it and it doesn't show up in my library any more.
However, the image and name still show up in the Material and Selection section. I shut down and restarted my system
and opened SketchUp17 and PlusSpec again. The image and ***** still show up. How do I remove it from there?
