Don't know if I asked this question before but here goes.  My "under construction" layout will be using GarGraves track with Ross switches.  I'm using O-54 for my outer loop, and O-42 for my inner loop.  GarGraves curves come in 45-degree segments for those two radii, but for the Ross switches, the O-42 is only 32 degrees, and the O-54 is only 30 degrees.  Do I have to cut a corresponding radii track section to make up the difference, or does Ross make a special track section that I'm not aware of?  If I cut the track, I'm assuming that the procedure would be to lay a curve section on the switch and mark where the switch ends.  Any help is greatly appreciated.

Ross has an O42X make up piece for the O42 switch to take it to 45° and O42P to bring it to parallel.

You'll have to cut for the O54.

read about Gargraves track specifications on their website. The diameter is "nominal" - not center rail like Ross. A Gargraves is a 54" diameter to the outside rail and the Ross is a 54" diameter on the center rail.

This is where software will help with the fitment for a build plan.

If you are going to use sectional track, I would suggest that you use all Ross.
