Torus

Toolbar: Draw 3D > Torus ()

Keyboard: TORUS

Alias: TOR, AI_TORUS

Experience Level: Intermediate

Draws a donut-shaped, three-dimensional entity. A torus is defined by two radius values: one for the tube and another from the center of the torus to the center of the tube.

Type torus to create a three-dimensional ACIS solid; type ai_torus to create a three-dimensional surface.

 

  1. Specify the center point of the torus.
  2. Specify the radius of the whole torus.
  3. Specify the radius of the tube.

You can draw a torus with no center, a self-intersecting torus, by specifying that the radius of the tube is greater than the radius of the torus.

 

An example of an intersecting torus.

Center of whole torus: Specify the center point of the torus.

Diameter ╖ <Radius of whole torus>: Specify a second point for the radius of the torus, or enter a value in drawing units. To specify the diameter of the whole torus, choose Diameter. The whole torus is measured from the center of the torus to the center of the tube.

Diameter ╖ <Radius of body of torus>: Specify two points for the radius of the body of the torus, or enter a value in drawing units. To specify the diameter of the body of the torus, choose Diameter. The body of the torus is the tube.

Number of longitudinal sections <16>: Enter the number of sections that are perpendicular to the xy plane. (This prompt displays only if you are using the ai_torus command to create a three-dimensional surface.)

Number of latitudinal sections<16>: Enter the number of sections that are parallel to the xy plane. (This prompt displays only if you are using the ai_torus command to create a three-dimensional surface.
