Draw a simple torus and label the “Radius” and the “Tube Radius.”

List three products that can be created using the TORUS command in AutoCAD.

Match the following misconceptions and answers.

• Why does it need two radii?

• One radius defines the torus size; the other, the tube thickness.

• What do you call one or more tori?

• A single is a "torus," multiple are "tori."

• Can I use a torus to create a oval shape

• Yes, blue grips modify torus size and shape.

• Can I edit a torus shape with the grips?

• Yes, a negative radius creates an elliptical torus.

Match the following modifiers with their purpose

• 3P (Three Points)

• Defines the circumference of the torus with three points that you specify.

• Specifies the center point of the torus.

• Defines the circumference of the torus with two points that you specify.

• TTR (Tangent, Tangent, Radius)

• Center Point

• Diameter

  2P (Two Points)

• Defines the torus with a specified radius tangent to two objects.

Reorder the following steps to create a torus.

• Create a torus by specifying the center.

• Specify the radius or diameter of the torus.

• Type "TOR" or press the "TORUS" command

• Specify the radius or diameter of the tube.
