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 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. Update viewIf checked, the helix will be shown in the view, and updated automatically on every change of the parameters. |
Properties
Below are properties which can be defined after creation of the feature.
- DataPitch: The axial distance between two turns.
- DataHeight: The total length of the helix (not accounting for the extent of the profile)
- DataTurns: The number of turns (do not need to be a whole number)
- DataLeft Handed:
- DataReversed: true or false. See Reversed.
- DataAngle: Not used.
- DataReference axis: The the helix axis
- DataMode: The helix input mode (pitch-height, pitch-turns, turns-height)
- DataOutside: Not used (Used in SubtractiveHelix)
- DataHas Been Edited: If false, the tool will propose an initial value for pitch based on the profile bounding box, so that self intersection is avoided.
- DataRefine: true or false. If set to true, cleans the solid from residual edges left by features. See Part RefineShape for more details.
- DataProfile: Either a sketch containing a closed contour, or a face.
- DataMidplane: Not used.
- DataUp to face: Not used.
- DataAllow multiple face: Not used.
