A torus can be assimilated to a small disc that makes a circular orbit around an imaginary axis. Thus the torus is defined by the following properties:
* {{PropertyData|Radius1:}} Radius of the circle around which the disc circulates.
* {{PropertyData|Radius1:}} Radius of the imaginary orbit around which the circular cross-section revolves.
* {{PropertyData|Radius2:}} Radius of the disc defining the form of the torus.
* {{PropertyData|Radius2:}} Radius of the circular cross-section defining the form of the torus.
* {{PropertyData|Angle1:}} 1st angle to cut / define the disc of the torus.
* {{PropertyData|Angle1:}} 1st angle to cut / define the disc of the torus.
* {{PropertyData|Angle2:}} 2nd angle to cut / define the disc of the torus.
* {{PropertyData|Angle2:}} 2nd angle to cut / define the disc of the torus.

Description

Inserts a subtractive torus in the active Body. Its shape is subtracted from the existing solid.

introduced in version 0.17

On the left: active body (A) shown in grey and subtractive torus (B) shown in transparent red; result on the right.

How to use

  1. Press the Subtractive Torus button. Note: the Subtractive Torus is part of an icon menu labelled Create an additive primitive. After launching FreeCAD, the Subtractive Box is the one displayed in the toolbar. To get the Torus, click on the down arrow besides the visible icon and select Subtractive Torus in the menu.
  2. Set the Primitive parameters and Attachment.
  3. Click OK.
  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

  • DataAttachment: defines the attachment mode as well as the Attachment Offset. See Part Attachment.
  • DataRadius1: Radius of the imaginary orbit around which the circular cross-section revolves.
  • DataRadius2: Radius of the circular cross-section defining the form of the torus.
  • DataAngle1: 1st angle to cut / define the disc of the torus.
  • DataAngle2: 2nd angle to cut / define the disc of the torus.
  • DataAngle3: 3rd angle to define the circumference of the torus.
