Thanks for the reply. I'll give your suggestions a shot.

I work for a manufacturing company and I build and render prototypes of the products we sell before we produce them for initial layouts and catalog purposes. Another purpose we use the models for is proofing products to customers before they buy. Our products come in several different colors and I've just started toying with DC's to make this easier on me after the initial setup.

I've been a big group fan...never getting into components. I've finally got the time to devote to learning more about them so I started yesterday with my pieces and doing an "On Click" material change. I'm running into two things that confuse me a bit. One is that when I duplicate a piece for my model and interact with it...on some of the pieces, all instances of that piece change. On other pieces, just THAT instance changes. I used the same SET formula for each...literally...i copied and pasted. So I'm confused as to why that is. Not that big a deal though.

The other thing...the more important part that has me stumped...is how can i have a DC that is made up of 3 different parts change colors all at the same time versus having to interact with each part in this DC? For example, I have a part that is made of (3) .75" thick boards. 2 of these are 10" wide and 47 tall and the other is 6" wide and 47 tall. I want them all to change as one...not each need interacting with.

How do I do such a thing?
