Helical Surface

(3D only) Used to construct a helical-shaped B-spline surface by sweeping a section profile curve along a helix curve.

You can access this tool from the following:

  • Ribbon: Modeling > Surfaces > Create Surfaces > Revolve Surface > Helix
  • Toolbox: Create Freeform Surfaces

Thread Sets the direction of the helix:
  • Right — The helix has a right-hand thread.
  • Left — The helix has a left-hand thread.
Base Radius If on, sets the base radius of the helix curve.
Top Radius If on, sets the top radius of the helix curve.
Pitch If on, sets the distance between each loop of the helix curve
Height If on, sets the overall height of the helix curve.
Tolerance If on, sets the tolerance for the B-spline surface.
