Torus

Insert Primitives Torus

The Torus command enables you to create a torus.

Obtaining a parametric solid or a surface
The final result of the command can be either a toroidal surfac or a parametric solid torus. The Associative Mode check box enables you to control the result:

When the box is checked, the resulting entity will be a parametric solid. A drive dimension will be associated with the length of the inner radius of the torus and one with the section radius. The icon of a solid will be displayed in the Model Structure.
When the box is cleared, the final result will be a toroidal surface.

To start the creation, you will have to specify a point to be used for the placement of the torus.

When the placement point is specified, a set of handles is displayed. At any time during the creation of the torus, you can:

Change the position of the placement point just by clicking in a different position.

Change the orientation of the torus. The three arcs represent the three angles of rotation (about each of the three orthogonal directions). You can rotate the torus about an axis by dragging the corresponding arc or by typing the value of the rotation into the Angle box which shows up when you pick the arc or also by using the X Axis, Y Axis, Z Axis drop-down lists under Axis Alignment:

Line	to align the axis to a line. Select the line.
2 points	to align the axis to the direction identified by the two points. Select the two points.
End point	to align the axis so that its second endpoint coincides with a point. Select the point.

Finally, you will have to define the length of the Inner radius and of the Radius. You can either type the value into the corresponding mini-dialog box, or define it interactively by dragging the corresponding handle.

A dynamic preview of the torus is displayed since the very moment you specify the placement point, so as to enable you to immediately assess the result of your actions.
