Hey Kevin,
Long road trip. I would first create an accurate mapping/drawing of the layout area with the dimensions marked. Doors that swing out/in, clearances required, etc. Use the text feature to mark the information on the plan. Objects>Special Objects>Text label
I think we all skipped past that part and began looking at the layout, assuming that you had all of that ironed out.
I just flipped you first pdf and added the information that you provided ( comments in your 3/7/16_9:25pm post) in notes. It's kind of awkward and inaccurate, especially when you will put many hours into designing a track plan to utilize the space to the maximum amount.
An example is the 2ft. walkway along the right side and top wall. That's kind of narrow for a walk around. Raising the layout height to, say, 42" and going under with an access hatch or two may work better and provide relief for the mechanical room and exterior door access by pushing the layout against those walls. Are there windows there that require access? ( I see the space in the wall markings)
