Enter a rotary-draw part as feed / rotate / bend (YBC) steps, then walk through it one bend at a time to see exactly how the plane-of-bend rotates at each stage — the part that gets hard to picture in your head after the third bend.
What this is — and isn't. This shows you the geometry and the rotation at every bend so you can judge the part yourself. It does not detect collisions or tooling interference, and makes no pass/fail claim. Rotation handedness depends on your machine's convention — check the first result against a part you already know, and use the handedness toggle if the twist appears mirrored.

#Feed YRot B° (±)Bend C°
Y = straight fed before the bend (mm). B = rotation of the bend plane. Dir = clockwise / counter-clockwise. C = bend angle. All bends use the bend radius above.
