Thanks for the help. I finally got everything sorted out. Didn't realize how deep I would have to dig into the nested component/group to change layer status. Thought just left selecting the whole group would be enough.

I think what really messed things up is that when working on one layer I would notice something wrong with a component on another layer and start editing it without explicitly changing layers, so now the new stuff would end up on the wrong layer. I guess I expected sketchup to automatically switch the working layer when I went in to edit components on particular layers. Seems like layers in sketchup aren't quite the same as they are in photoshop.

I'm having trouble getting a group/component to stick to a layer. If I select the group the entity info indicates it's on layer 0, but if I turn visibility on layer 1 off then the group disappears. The group is made up of various components and it appeared at one point that some of those components where part of layer 1, but I switched them to layer 0, and still no dice.

I'm sure I've really hacked things up here, so any other advice is appreciated.
