Helix/Spiral PropertyManager

You define helix and spiral parameters in the Helix/Spiral PropertyManager.

To open this PropertyManager:

  1. In a part, select a sketch that contains a circle.
  2. Click Helix and Spiral (Curves toolbar) or Insert > Curve > Helix/Spiral .

Defined By

Specifies the type of curve (helix or spiral) and which parameters to use to define the curve. Select one of the following:

Pitch and Revolution Creates a helix defined by Pitch and Revolutions.
Height and Revolution Creates a helix defined by Height and Revolutions.
Height and Pitch Creates a helix defined by Height and Pitch.
Spiral Creates a spiral defined by Pitch and Revolutions.


Sets parameters of the curve. Your selection under Defined By determines which parameters are available.

Constant pitch (Helix only.) Creates a helix with a constant pitch.
Variable pitch (Helix only.) Creates a helix with a pitch that varies based on the region parameters you specify in the table below.
Region parameters (Variable pitch helix only). Sets the number of revolutions (Rev), height (H), diameter (Dia), and pitch (P) for regions along the helix. Parameters that are inactive or for information only are shown in gray.
Height (Helix only.) Sets the height.

For helixes:

Sets the distance between turns.

For spirals:

Sets the radial distance between revolutions of the curve.

Revolutions Sets the number of turns.
Reverse direction

For helixes:

Extends the helix backwards from the point of origin.

For spirals:

Creates an inward spiral.

Start angle Sets where to start the first turn on the sketched circle.
Clockwise Sets the direction of the turns to clockwise.
Counterclockwise Sets the direction of the turns to counterclockwise.

Taper Helix

Creates a tapered helix. (Available only for constant pitch helixes.) Select Taper Helix.

Taper Angle Sets the angle of the taper.
  Taper outward Tapers the helix outward.
