Description
The Helix tool creates a solid by sweeping a selected sketch or 2D object along a helix path.
The profile (B), is swept around axis (A) in order to produce the solid helix (C)
Usage
- Select the sketch to be swept into a helix. A face on the existing solid can alternatively be used.
- Press the File:PartDesign Additive Helix.svg AdditiveHelix button.
- Set the Helix parameters (see next section).
- Press OK.
Options
When creating an Additive Helix, the Helix parameters dialogue offers several parameters specifying how the sketch should be swept.
![]() |
AxisThis option specifies the axis about which the sketch is to be swept.
ModeThis controls what parameters will be used to define the helix, Allowable choices are: Pitch-Height, Pitch-Turns and Height-Turns. PitchThe distance between turns in the helix. HeightThe height of the helix (center-center). TurnsThe number of turns in the helix. Define as Height/Pitch Left handedIf checked, the turning direction of helix is reversed from default clockwise to counterclockwise. ReversedIf checked, the axis direction of helix is reversed from default. |
Properties
Below are properties which can be defined after creation of the feature. Data properties Base and Axis are uneditable.
- DataAngle: angle of rotation. See Angle.
- DataLabel: label given to the operation, can be changed at convenience.
- DataMidplane: true or false. See Symmetric to plane.
- DataReversed: true or false. See Reversed.
- DataRefine: true or false. If set to true, cleans the solid from residual edges left by features. See Part RefineShape for more details.
