Make a drawing (sideview), figure out which part of the centerline has a
and [Degrees bend]/360 x 2 x Pi x Radius will give you an first
the straight lenght of the curved bit. Real lenght is probably slightly less as
the neutral bending line doesn't quite follow the centerline, but with short
bends this can usually be ignored.
