Okay, I figured it out. In a test file, I got a the camera to orbit a small piece of equipment exactly like I wanted. The key was being able to position the camera...AND aim it at a common fixed point. I knew you could position the camera and create a scene, but I was not aware that you could click, then drag the view of the camera to a fixed point. That was the piece I was missing. Once I figured that out, everything fell into place. No plugins were necessary, as was mentioned. Thanks for the help, and if you were trying to get me to see the point above and I just missed it, my apologies.

Thanks very much Rich & Cotty -- I certainly appreciate the feedback. I don't know why it was so difficult for me to find this important info without having to come here, register, and ask point blank. It almost seems as if Trimble really would rather folks not be aware of these distinctions up front. ~ too bad.
