Kevin,
I entered the measurements as best I could. You didn't have a measurement for E, there were 3 D's, there was no F, F seemed like it should have been one of the D's so I filled them in to match the original fairly closely and there was no measurement for the lower left between A and N. I think I got them, but you can double-check. The black in the original, the green is the new and relative to the lower 24":24" corner of the workspace. I then added the purple to show what is the actual floor space that can be used allowing for the doors and captured a separate photo. In your original there is a post or something in the middle and I don't know exactly where it is, if that's what it is. I then moved all the track so there is 24" access on the bottom and right side. I did not draw a new tabletop because it's obvious changes will be needed and we still don't know if you want the tabletop to allow for 24" access all around or what. Sorry, but I need to pack for our trip tomorrow and do some things with the car, so I'll be scarce until Friday. Good luck and HTH.
