Описание

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

Применение

See Part Primitives.

Example

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

Properties

See also: Property editor.

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

• ДанныеGrowth (Length): The distance between two consecutive turns of the spiral. The default is 1mm.
• ДанныеRadius (Length): The start radius of the spiral, the distance between its center and its start point. Can be 0mm. The default is 1mm.
• ДанныеRotations (QuantityConstraint): The number of rotations, or turns, of the spiral. The default is 2.
• ДанныеSegment 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()
