By the way, I added the words for the acronyms for my mother. I know my typical readers know what they mean but she reads this blog too sometimes and its bad enough that most everything is gibberish anyway but I have to use acronyms too?!?
What I do is sketch a short piece of duct/pipe from a connector on the equipment so that I can cheat and use the offset parameter of the duct/pipe to raise the equipment to the correct elevation that I need (Video?).
