The basics of applying bend functions  The FABRICATOR
The outside setback is a dimensional value that begins at the tangent of the radius and the flat of the leg, measuring to the apex of the bend (see Figure 2). At 90 degrees, it does not matter if you use the included or complementary angle; you still end up with 45 degrees, and you get the same OSSB answer.
