Hi Guys: Making some progress on SketchUp, I now can manipulate objects and place them where I want without too much difficulty. Thanks to all who answered with my noob questions. Still drives me nuts in a few ways , though: 1. If I copy holes from one object to another, it seems to be a crapshoot whether they will end up as being holes or just circles on the surface. If they are circle, they don't seem to "penetrate" the surface, that is they don't split the surface into an "inside" and an "outside". I have to fratz with them forever to finally get it to be a hole. This seems to occur whether I copy them to a 3d surface or a plane before extruding. ***? 2. It is so annoying to be zooming out from something to get a better look and end up inside another object. It is excruciatingly slow to zoom back out again for some reason. The zoom seems to change from "high gear" when you have your cursor over an object to "low gear" when you have your cursor in free space or when it is inside a 3d object. Is there any way to make surfaces temporarily "impenetrable" so your zoom just stops when you hit something? 3. Components seem to be handy, but when you create a component and give it a name, does it go into a library somewhere? Can you select components from the library and import them into your drawing? So far the only way I have found to do this is to open another instance of SketchUp, load the component, then use Edit/Copy, switch back to my model, and use Edit/Paste. There has got to be a better way. If not, what the hell is the point of making components?
