Yesterday while taking breaks from winter leaf cleanup and getting the mower running, I laid out my GarGraves track on the floor in an approximation of how the plan flows. It is not exact, because I just laid pieces overlapping where there will be track cuts, and I did not bend any of the flex to shape. I used some 054 and 072 I had on hand to simulate the bent track. I also only have 4 of the 9 switches, so only one is in place. I also left the staging sidings out. Here are a couple of photos of how the track will fill the space. Not too bad. I think I can live with this as long as I make the layout high enough to get my increasingly arthritic body under and into the access hatches. 
Sorry the room is so small I couldn't get a complete view. It was too windy or I would have opened the sliding glass door. I didn't want dried leaves and maple blossoms blowing in. I think you get the idea.
