Thanks, Andy for taking the time to produce the image. Being a visual person this animation really helps me understand the process quickly, saving me a great deal of time.
Not to tell you what you should do, however my feelings are basic construction techniques such as this example animation, might serve all beginners well if they were posted as tutorials (Or How-to's) on the home page, or where the ever the tutorials are listed, as they become lost amount the posted messages (I have made a AC3D folder with all the worthwhile suggestions).
In addition, the AC3D PDF manuals could be updated to include many of the things discovered on the message boards so that all such things are all in one in place, anyway thanks much for your constant and greatly appreciated helpfulness for us all.
