Actually that question was just an afterthought. What I really need help with is my components window list. It's crazy. I make three instances of a component and the list still shows zip instances. It will highlight the three copies when I check for instances, but it won't count them. I want to delete a component, and it won't give me that option. Or maybe it will, if I check back later. Who knows? The outer rim is composed of 61 "instances" of a component - it shows a thumbnail of the complete outer rim, with 61 instances. It's the complete rim, it should show zero instances, right? It shows a thumbnail of the component used to make the rim, no instances. Shouldn't it show 61 instances for that? There are 5 lugnuts, each a copy of the original component. It shows only 1 in the list, which is fine, but with no instances. The tire is made up of 42 copies of a component - there is a thumbnail for one of those components, showing no paint on the reverse faces - no instances. There's another thumbnail of it, showing painted reverse faces - 1 instance. But if I delete either of these components, the entire tire goes away. There just seems to be no logic to all this, no rhyme or reason, at least not to me. Instead of the list being a helpful component management tool, all it does is confuse me and raise my blood pressure. I know it probably has something to do with the way I do things when I'm creating a model, probably very basic stuff I'm doing wrong, but I need to know what that something is, now, before I go any further and make things even worse. I've looked in the books, I've searched the web, all they seem to offer is basic info on the subject, no comprehensive insights or tips, nothing in depth, nothing that comes close to answering my questions. My frustration level is very high and rising daily. I need for someone to help me make some sense of all this.
