I deleted all the base cabinet parts but The back & Top, Rezized to resemble a L Cleat & Saved. I install it in the corners (rezise if nessasary when installing in room layout) where there is no cabinet node so when creating countertops I can get it to go into such corners etc. You've got to pay attention to the install highth from floor when installing.
( HMMM .... for some reason when I try to save images in Jpg It always seems the windows window is partialy or completely visible ... )
Now I understand. I use a filler which is just the back of a cabinet, from 1/4 \" material and about 1/4\" wide. This keeps me from having to worry about the install height.
I simply delete everthing except the back no toe kick, and make the cabinet 1/4\" wide.
