|Part Design → Create an additive primitive → Additive Torus|
|Introduced in version|
|PartDesign CompPrimitiveAdditive, PartDesign SubtractiveTorus|
Inserts a primitive torus in the active Body as the first feature, or fuses it to the existing feature(s).
- Press the Additive Torus 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.
- Set the Primitive parameters and Attachment.
- Click OK.
- A Torus feature appears under the active Body.
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.
- DataAttachment: defines the attachment mode as well as the Attachment Offset. See Part EditAttachment.
- DataLabel: Label given to the Torus object. Change to suit your needs.
- DataRadius1: Radius of the imaginary orbit around which the circular cross-section revolves. (The distance between the center of the torus and the center of the revolving cross section)
- DataRadius2: Radius of the circular cross-section defining the form of the torus.
- DataAngle1: (labelled V parameter in the Primitive parameters) lower truncation of the torus, parallel to the circular cross section (-180 degrees in a full torus). A bug in the sources causes unexpected results at changing Angle1.
- DataAngle2: (unlabelled in the Primitive parameters) upper truncation of the ellipsoid, parallel to the circular cross section (180 degrees in a full torus). A bug in the sources causes unexpected results at changing Angle2.
- DataAngle3: (labelled U parameter in the Primitive parameters) angle of rotation of the circular cross section (360 degrees in a full torus).
