Description

The Part Torus command creates a parametric torus solid, a doughnut shape. It is the result of sweeping a circular profile around a circular path. In the coordinate system defined by its DadosPlacement property, the circular path of the torus lies on the XY plane with its center at the origin.

A Part Torus can be turned into a segment of a torus by changing its DadosAngle3 property. By changing its DadosAngle1 and/or DadosAngle2 properties the swept profile can become a segment of a circle.

Usage

  1. There are several ways to invoke the command:
    • Press the Torus button.
    • Select the Part → Primitives → Torus option from the menu.
  2. The Torus object is created.
  3. Optionally change the dimensions and DadosPlacement of the torus by doing one of the following:
    • Double-click the object in the Tree view:
      1. The Geometric Primitives task panel opens.
      2. Change one or more properties.
      3. The object is dynamically updated in the 3D view.
      4. Press the OK button to close the task panel.
    • Change the properties in the Property editor.
    • Change the DadosPlacement with the Std TransformManip command.

Example

Part Torus from the scripting example

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

Notes

  • A Part Torus can also be created with the Part Primitives command. With that command you can specify the dimensions and placement at creation time.

Properties

See also: Property editor.

A Part Torus 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.

Torus

  • DadosRadius1 (Length): The radius of the circular path of the torus. The default is 10mm.
  • DadosRadius2 (Length): The radius of the circular profile of the torus. The default is 2mm.
  • DadosAngle1 (Angle): The start angle of the circular profile. Valid range: -180° <= value <= 180°. The default is -180°.
  • DadosAngle2 (Angle): The end angle the circular profile. Valid range: -180° <= value <= 180°. The default is 180°. If the total angle of the circular profile is smaller than 360° the profile will have a pie-shape.
  • DadosAngle3 (Angle): The angle of the circular path of the torus. Valid range: 0° < value <= 360°. The default is 360°. If it is smaller than 360° the resulting solid will be a segment of a torus.

Scripting

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

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

torus = FreeCAD.ActiveDocument.addObject("Part::Torus", "myTorus")
  • Where "myTorus" is the name for the object.
  • The function returns the newly created object.

Example: 

import FreeCAD as App

doc = App.activeDocument()

torus = doc.addObject("Part::Torus", "myTorus")
torus.Radius1 = 20
torus.Radius2 = 10
torus.Angle1 = -90
torus.Angle2 = 45
torus.Angle3 = 270
torus.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(30, 45, 10))

doc.recompute()
