Here is my basement shop I laid out in SU. If you look at some of the other tabs I input the overhead floor joists and steel beams. I originally did this for layout purposes to show where I could run duct work for a DC system when I got one. Just wanted to share it and say thanks to Dave R for all the help and adivce.
