Описание

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

PartDesign SubtractiveTorus example.svg

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

Применение

  1. Press the PartDesign SubtractiveTorus.svg 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.

Опции

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.

Свойства

  • ДанныеAttachment: defines the attachment mode as well as the Attachment Offset. See Part EditAttachment.
  • ДанныеLabel: Label given to the Torus object. Change to suit your needs.
  • ДанныеRadius1: 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)
  • ДанныеRadius2: Radius of the circular cross-section defining the form of the torus.
  • ДанныеAngle1: (labelled V parameter in the Primitive parameters) lower truncation of the torus, parallel to the circular cross section (-180° in a full torus). A bug in the sources causes unexpected results at changing Angle1.
  • ДанныеAngle2: (unlabelled in the Primitive parameters) upper truncation of the ellipsoid, parallel to the circular cross section (180° in a full torus). A bug in the sources causes unexpected results at changing Angle2.
  • ДанныеAngle3: (labelled U parameter in the Primitive parameters) angle of rotation of the circular cross section (360° in a full torus).
