Some tips related to this pattern::
- Helixes are not developable surfaces.
- Cold deformation in the Z direction is considered, (perpendicular to the sheet metal surface), without thinning nor stretching of the metal sheet.
- The bending is linear. The helix pitch should be less than the outside diameter.
