Helix Parameters

To sketch a helix, specify these parameters:

Axis position Defines the helix position. Specify the axis base center point and end point.
Base radius or Base diameter Defines the helix base (the circle created by the helix when seen from the top) by specifying the base radius or diameter.
Top radius or Top diameter Defines the helix top circle by the top radius or diameter. The base and top radii or diameter must not be zero.
  • To create a cylindrical helix, specify the same value for both the base radius (or diameter) and top radius (or diameter).
  • To create a conical helix, specify different values for the base radius (or diameter) and top radius (or diameter).
Height Defines the helix height and the direction in the Z axis.
  • Positive Value. Creates the helix (spiral) towards the positive direction of the Z axis.
  • 0 (zero). Creates a 2D spiral.
  • Negative value. Creates the helix (spiral) towards the negative direction of the Z axis.
Revolutions Specifies the number of revolutions for the helix. After specifying the height, the command draws the specified number of revolutions evenly distributed.
Pitch Specifies the distance between two revolutions, measured along the helix axis. If you specify a pitch, the number of revolutions is automatically calculated. The higher the pitch is the lower the number of revolutions.
Direction

Defines the direction in which the helix is twisted: clockwise (CW) or counterclockwise (CCW).
  • P1 - Axis position
  • R - Base radius
  • r - Top radius
  • H - Height
  • p - Pitch

Number of revolutions = 3
