For Rev-A-Shelf, you have to open their .dwg files and "explode" them to break them into separate parts and save the parts to different layers so that when you convert them to .stl to bring into eCabinets you can texture the individual parts.
If you don't explode then your model can only have one texture.
I didn't' find a wire basket in rev-a-shelf but here is one of their plastic ones. I did this quickly so it isn't perfect. (i missed some of the parts) You can scale it to size in eCabinets. Unzip the files and place them in your import folder.
George Davidson has some real nice looking wire stuff if this doesn't work.
