A [[Image:Part_Helix.svg|24px]] '''Part Helix''' is a parametric shape that can be created with the [[Image:Part_Primitives.svg|24px]] [[Part_Primitives|Part Primitives]] command. In the coordinate system defined by its {{PropertyData|Placement}} property, the axis of the helix matches the Z axis and its bottom point, the start point, lies on the X axis. |

A common usage for the helix primitive is for [[Thread_for_Screw_Tutorial|creating screw threads]] in conjunction with a closed profile, and the {{Button|[[Image:Part_Sweep.svg|16px]] [[Part_Sweep|Sweep]]}} operation. This process works essentially the same in the [[PartDesign_Workbench|PartDesign Workbench]] by using the {{Button|[[File:PartDesign_AdditivePipe.svg|16px]] [[PartDesign_AdditivePipe|PartDesign Additive pipe]]}} tool. |

* {{Parameter|Height:}} The height corresponds to the overall height of the helix measured along the main axis of the helix. |

* {{Parameter|Radius:}} The radius corresponds to the radius of the circle built by the helix by viewing the helix from the top or bottom. |
|||
* {{Parameter|Angle}}: Per default the helix is built on a imaginary cylinder. With this option it is possible to build the helix on a imaginay cone. This angle corresponds to the angle of the cone. The value must be comprised between 0 and +90 deg. |

* {{Parameter|Right-handed or Left-handed:}} This parameter specifies the [https://en.wikipedia.org/wiki/Screw_thread handedness] of the helix. |

Description
A Part Helix is a parametric shape that can be created with the Part Primitives command. In the coordinate system defined by its DataPlacement property, the axis of the helix matches the Z axis and its bottom point, the start point, lies on the X axis.
Usage
See Part Primitives.
Example
A Part Helix object created with the scripting example below is shown here.
Notes
- A Part Helix can be used to create screw threads. See Thread for Screw Tutorial.
Properties
See also: Property editor.
A Part Helix object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:
Data
Attachment
The object has the same attachment properties as a Part Part2DObject.
Coordinate System
- DataLocal Coord (
Enumeration
): The handedness, or direction, of the helix:Right-handed
orLeft-handed
. The default isRight-handed
, meaning the helix turns counterclockwise as it goes up.
Helix
- DataPitch (
Length
): The distance between two consecutive turns of the helix measured along its Z axis. The default is1mm
. - DataHeight (
Length
): The height of the helix. The default is2mm
. - DataRadius (
Length
): The start radius of the helix. The helix has a constant radius if DataAngle is0°
. - DataSegment Length (
QuantityConstraint
): The number of turns per helix subdivision. The default is1
, meaning each full turn of the helix is a separate segment. Use0
to suppress subdivision. - DataAngle (
Angle
): The angle that defines of the outer shape of the helix. Valid range:-90° < value < 90°
. The default is0°
. If it is0°
the helix is cylindrical, else it is conical.
Scripting
See also: Autogenerated API documentation, Part scripting and FreeCAD Scripting Basics.
A Part Helix can be created with the addObject()
method of the document:
helix = FreeCAD.ActiveDocument.addObject("Part::Helix", "myHelix")
- Where
"myHelix"
is the name for the object. - The function returns the newly created object.
Example:
import FreeCAD as App
doc = App.activeDocument()
helix = doc.addObject("Part::Helix", "myHelix")
helix.Pitch = 2
helix.Height = 3
helix.Radius = 4
helix.SegmentLength = 21
helix.Angle = 45
helix.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(75, 60, 30))
