Description
A Part Spiral is a parametric shape that can be created with the
Part Primitives command. In the coordinate system defined by its DadosPlacement 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

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
- DadosGrowth (
Length): The distance between two consecutive turns of the spiral. The default is1mm. - DadosRadius (
Length): The start radius of the spiral, the distance between its center and its start point. Can be0mm. The default is1mm. - DadosRotations (
QuantityConstraint): The number of rotations, or turns, of the spiral. The default is2. - DadosSegment Length (
QuantityConstraint): The number of turns per spiral subdivision. The default is1, meaning each full turn of the spiral is a separate segment. Use0to 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()
