We're building a storage rack to hold laminate sheets at our shop and I want to create a 3D model of the wood frame. I'm doing this using 3D solids. The problem is the material (fir-framing) is merging with each adjacent piece of the frame so you can't distinguish one piece from the next in any 3D rendering views. How do I keep the material layer from merging so you can see each individual part?

Is there a way to "ignore" columns like Room Name that we know are going to be different but want to group similar items anyway and still display those columns that have the differences? For example, I want all 2668 R In doors to be grouped together, but I want to display the different room names for those doors in the column and not have a separate row for each door.
