Part Torus

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 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 property. By changing its and/or  properties the swept profile can become a segment of a circle.



Usage

 * 1) There are several ways to invoke the command:
 * 2) * Press the button.
 * 3) * Select the option from the menu.
 * 4) A torus is created.
 * 5) Optionally change the dimensions and  of the torus by doing one of the following:
 * 6) * Double-click the object in the Tree view:
 * 7) *# The task panel opens.
 * 8) *# Change the required properties.
 * 9) *# The object updates dynamically in the 3D view.
 * 10) *# Press the button.
 * 11) * Change the properties in the Property editor.
 * 12) * Change the with the [[Image:Std_TransformManip.svg|16px]] Std TransformManip command.

Example


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

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
The object has the same attachment properties as a Part Part2DObject.


 * : The radius of the circular path of the torus. The default is.
 * : The radius of the circular profile of the torus. The default is.
 * : The start angle of the circular profile. Valid range: . The default is.
 * : The end angle the circular profile. Valid range: . The default is . If the total angle of the circular profile is smaller than the profile will have a pie-shape.
 * : The angle of the circular path of the torus. Valid range: . The default is . If it is smaller than the resulting solid will be a segment of a torus.

Scripting
A Part Torus can be created using the following function:


 * Where is the user editable name for the object.
 * The function returns the newly created object.

The label text of the object can be easily changed by

You can access and modify attributes of the object. For example, you may wish to modify the radii or angle parameters.

The result will be a three-quarter torus.

You can change its placement and orientation with:
