PartDesign AdditiveTorus

Description
Inserts a primitive torus in the active Body as the first feature, or fuses it to the existing feature(s).



How to use

 * 1) Press the  button. Note: the Additive Torus is part of an icon menu labelled Create an additive primitive. After launching FreeCAD, the Additive Box is the one displayed in the toolbar. To get the Torus, click on the down arrow besides the visible icon and select Additive Torus in the menu.
 * 2) Set the Primitive parameters and Attachment.
 * 3) Click.
 * 4) A Torus feature appears under the active Body.

Options
The Torus can be edited after its creation in two ways:
 * Double-clicking it in the Model tree, or by right-clicking and selecting Edit primitive in the contextual menu; this brings up the Primitive parameters.
 * Via the Property editor.

Properties

 * : defines the attachment mode as well as the Attachment Offset. See Part Attachment.
 * : Label given to the Box object. Change to suit your needs.
 * Radius of the circle around which the disc circulates.
 * Radius of the disc defining the form of the torus.
 * (labelled V parameter in the Primitive parameters) lower truncation of the torus, parallel to the circular cross section (-180 degrees in a full torus)
 * (unlabelled in the Primitive parameters) upper truncation of the ellipsoid, parallel to the circular cross section (180 degrees in a full torus).
 * (labelled U parameter in the Primitive parameters) angle of rotation of the circular cross section (360 degrees in a full torus).
