Menu : CURVE

Command: Design:Spiral

Shortcut : None

This command creates a 3D spiral curve. A parameter box appears requesting how many loops the spiral should contain, as well as the pitch and diameter of each loop.

One use for such a curve is for creating a spiral surface by 3D building. This would be achieved by creating a spiral in a 3D-projection curve set and a circle in the cross-section curve set.
