Description

A Part Spiral is a parametric shape that can be created with the Part Primitives command. In the coordinate system defined by its DatosPlacement property, the spiral lies on the XY-plane with its center at the origin and its start point on the X-axis. It widens as it turns counterclockwise.

Usage

See Part Primitives.

Example

Part Spiral from the scripting example

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

Properties

See also: Property View.

A Part Spiral 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.

Spiral

• DatosGrowth (Length): The distance between two consecutive turns of the spiral. The default is 1mm.
• DatosRadius (Length): The start radius of the spiral, the distance between its center and its start point. Can be 0mm. The default is 1mm.
• DatosRotations (QuantityConstraint): The number of rotations, or turns, of the spiral. The default is 2.
• DatosSegment Length (QuantityConstraint): The number of turns per spiral subdivision. The default is 1, meaning each full turn of the spiral is a separate segment. Use 0 to suppress subdivision.

Scripting

See also: Autogenerated API documentation, Part scripting and FreeCAD Scripting Basics.

A Part Spiral can be created with the addObject() method of the document:

spiral = FreeCAD.ActiveDocument.addObject("Part::Spiral", "mySpiral")

• Where "mySpiral" is the name for the object.
• The function returns the newly created object.

Example:

import FreeCAD as App

doc = App.activeDocument()

spiral = doc.addObject("Part::Spiral", "mySpiral")
spiral.Growth = 2
spiral.Radius = 3
spiral.Rotations = 4
spiral.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(75, 60, 30))

doc.recompute()
