Example

A Part Helix object created with the scripting example below is shown here.

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

• ДанныеLocal Coord (Enumeration): The handedness, or direction, of the helix: Right-handed or Left-handed. The default is Right-handed, meaning the helix turns counterclockwise as it goes up.

Helix

• ДанныеPitch (Length): The distance between two consecutive turns of the helix measured along its Z axis. The default is 1mm.
• ДанныеHeight (Length): The height of the helix. The default is 2mm.
• ДанныеRadius (Length): The start radius of the helix. The helix has a constant radius if ДанныеAngle is 0°.
• ДанныеSegment Length (QuantityConstraint): The number of turns per helix subdivision. The default is 1, meaning each full turn of the helix is a separate segment. Use 0 to suppress subdivision.
• ДанныеAngle (Angle): The angle that defines of the outer shape of the helix. Valid range: -90° < value < 90°. The default is 0°. If it is 0° 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))

doc.recompute()
