90° BA preview
BA = angle × (CLR + K × wall). Higher K = longer BA = shorter legs. Use Measured Leg Correction after a test bend to calibrate for your actual bender.
Bend Setup
D = pipe OD. 1.5D is tightest common die.

Degrees to rotate the tube around its own axis before clamping for this bend. Measured from the cut end of the pipe looking toward the bend — positive = clockwise (right-hand rule), negative = counter-clockwise.
On the bender: after completing the previous bend, loosen the clamp, rotate the tube by this amount before re-clamping for the next bend.
0° = same plane as previous bend  ·  90° = quarter turn  ·  180° = flip (reverse direction)  ·  −90° = quarter turn opposite way
