Geometry aid onlyUse the take-up and bend data for the actual bender, and verify final dimensions with a test bend.

Method and field check

True offset is the hypotenuse of the measured horizontal and vertical offsets. Rotation is the arctangent of vertical over horizontal offset. Mark spacing and shrink use the entered bender multiplier and shrink factor. Verify the rotation plane and bender marks in the field.
