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.
