Part Torus/fr

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



How to use
In the Part workbench click on the torus icon. 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 paragraph.

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:


 * Radius of the circle around which the disc circulate
 * Radius of the disc defining the form of the torus
 * 1nd angle to cut / define the disc of the torus
 * 2nd angle to cut / define the disc of the torus
 * 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 radius 1 has a value of 20 mm.

The parameter radius 2 has a value of 2 mm.

The parameter angle 1 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 angle 2 has a value of 90°.

The parameter angle 3 has a value of 90°.
