Thanks, Michael, for the additional help.

But yes, indeed, Marc hit the nail on the head, right from the start.

I'm slowly getting to a point where I'm able to do more of the prep work on my clients' CAD files, than I had previously been able to accomplish. This has the potential to both increase the quality of my finished renders, and save me hours of trying to do the same thing in my animation system. So, enjoying MOI so far!
