## Belts
Models timing belt running over toothed or smooth pulleys and calculates an accurate length.
Only models 2D paths, so not core XY!
Only models 2D paths, so not crossed belt core XY!
To make the back of the belt run against a smooth pulley on the outside of the loop specify a negative pitch radius.
