Bend lines on sheet metal spiral (Auger)

I have created a helix spiral using 2 helix' & then converting their edges in 2 seperate 3D sketches. (

Using lofted sheet metal, I've been able to create the flat pattern for the auger flight section but I can't get any bend lines for a press brake.


Is there any work around for this, has anyone encountered this problem before?


There's a video showing a company using specialist equipment to press their flights but I'm hoping to get away with regular press brake.

The problem is that I've no idea where to press the part.
