The largest diameter on my floor layout is 0-81. The majority is O72.

The 81 is not really 81" center rail to center rail, and the O72 isn't either. Found this out by things 'just not working' using an AutoCad knockoff to design the layout, and things just not coming up right. At some point I made a ring of both, measured center to center, then another 90°, then used the average for my drawings. I had to adjust the ring several times to get it as close to a circle as I could with the tape measure. Tubular track is just, will, yeah, close enough.
