Description

A Part Torus can be turned into a segment of a torus by changing its DatosAngle3 property. By changing its DatosAngle1 and/or DatosAngle2 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 is created.
3. Optionally change the dimensions and DatosPlacement 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.
   • Change the properties in the Property editor.
   • Change the DatosPlacement with the Std TransformManip command.

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

• DatosRadius1 (Length): The radius of the circular path of the torus. The default is 10mm.
• DatosRadius2 (Length): The radius of the circular profile of the torus. The default is 2mm.
• DatosAngle1 (Angle): The start angle of the circular profile. Valid range: -180° <= value <= 180°. The default is -180°.
• DatosAngle2 (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.
• DatosAngle3 (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()
