Pattern: helix - Dialog - Input parameters
Parameter input form
Settings:
- Ends 1 & 2 dimensions: External
- Development precision [divisions]: 96
- DXF text height: 2.5
- Input and drawing file units: Millimeters
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.
