Explanation of Input Boxes
Note: All dimensional units must be the same. Inches, meters, etc.
Crossing Angle (degrees)
At zero degrees the tracks are parallel and would never cross.
90 degrees is a perfect 4-way intersection.
Normal Tie Length
The length of a normal track tie. Crossover ties will progressively
get longer from each end.
The measurement from tie to tie, not the gap between them. It is the
center to center distance. The width of ties is not needed.
Snap to Nearest Unit
This allows you to select how much precision you need. The tie length
will be rounded to the nearest unit you select here.
