Conduit Bend Offset Formula
A two-bend conduit offset is right-triangle geometry. The calculator applies the offset multiplier, shrink and bend-budget checks for the selected angle.

Offset multiplier
multiplier = 1 / sin(angle)
Distance between marks
D = offset_height / sin(angle)
Shrink allowance
shrink = offset_height * tan(angle / 2)
