Description

Creates a simple parametric torus, with position, angle1, angle2, angle3, radius1 and radius2 as parameters.

Usage

1. Switch to the Part Workbench
2. Invoke the command several ways:
   • Press the button in the toolbar.
   • Select the Part → Primitives → Torus from the menu bar.
   • Select Part → Creates primitives... then choose Torus from the Geometric Primitives task panel.

Result: The torus will be positioned at origin (point 0,0,0) on creation.
The angle parameters (angle1, angle2, angle3), as well as the radius parameter (radius1 , radius2) parameters permit to parametrize the torus, see next section.

Option

Parameter

A torus can be assimilated to a small disc that makes a circular orbit around an imaginary axe. Thus the parametric torus is defined by the following parameters:

• Radius1: Radius of the circle around which the disc circulate
• Radius2: Radius of the disc defining the form of the torus
• Angle1: 1st angle to cut / define the disc of the torus
• Angle2: 2nd angle to cut / define the disc of the torus
• Angle3: 3rd angle to define the circumference of the torus.

as well as the standard set of placement parameters. The pictures below give a visual overview of the parameters antecedently mentioned:

The parameter Radius1 has a value of 20 mm.

The parameter Radius2 has a value of 2 mm.

The parameter Angle1 has a value of -90°. Notice that, the "angle measure" tool cannot display negative angle. Considered the displayed value in picture as "-90°".

The parameter Angle2 has a value of 90°.

The parameter Angle3 has a value of 90°.
