Bill, I finally figured it out. When I make the CAD BLOCK, the CAD BLOCK lines, fills etc must be on the PLANT LAYER, which is the layer the plant itself will be on.
Except for the good cad block, all the other cad block items I had drawn were on the CAD LAYER, that is why they did not work. A very subtle difference, but very valuable to understand.
So, if I were to move my plant from the plant layer to the INDOOR PLANT LAYER, I would lose the ability to control the line wts, styles and colors because the cad lines for the cad block were on the PLANT LAYER and not the INDOOR PLANT LAYER.
Wow, who would of thunk it...........
suppose you wanted to move that plant to the INDOOR PLANT LAYER, you would be able to control it via THAT LAYER by changing from BLOCK SETTING TO IMAGE SETTING, but.... but.... but... now you give up the fills.
Thanks for the help Bill. Hope the home show is going well for you and you are netting some good leads.
