Create a ring-shaped solid that resembles the inner tube of a tire.
A torus has two radius values. One value defines the tube. The other value defines the distance from the center of the torus to the center of the tube. By default, a torus is drawn parallel to and is bisected by the XY plane of the current UCS.
A torus can be self-intersecting. A self-intersecting torus has no center hole because the radius of the tube is greater than the radius of the torus.
Torus Creation Options
Use the following options to control the size and rotation of the tori you create.
- Set the size and plane of the circumference or radius. Use the 3P (Three Points) option to define the size of the torus anywhere in 3D space. The three points also define the plane of the circumference. Use this option to rotate the torus as you create it.
- Set the circumference or radius. Use the 2P (Two Points) option to define the size of the torus anywhere in 3D space. The plane of the circumference matches the Z value of the first point.
- Set the size and location of the torus based on other objects. Use the Ttr (Tangent, Tangent, Radius) option to define a torus that is tangent to two circles, arcs, lines, and some 3D objects. The tangency points are projected onto the current UCS.
