... , V-crossing angle, V-crossing type, V-crossing entry straight, and other settings. Most significantly of course they also change as you curve the turnout. Now that you are using Templot you will tend to make far more curved turnouts than straight ones, so the radii will all be different. Here is a very odd size turnout, a B5, which you wouldn't normally think of using -- it is "all switch and no crossing", but it illustrates the different radii within it: 00_b5_radii.png The read-out at A shows the smallest radius anywhere in the turnout, and flashes red if it is below the limit you have set as a warning. The read-out at B shows the curving radius in the main road of the turnout. The read-outs at C and D show the the radius for the switch and the turnout section respectively. You can see that because it is a funny B5 size, D is much smaller than C, and is also the radius showing at A. Here ...
