• Specify the Axis Start Point.

• Specify the Axis Endpoint.

• Specify the degrees.

Match the following modifiers with their correct descriptions:

• Start Angle

• Specifies an offset for the revolution from the plane of the object being revolved.

• Axis Start Point

• Specifies the objects to be revolved about an axis.

• Object, “O”

• Specifies the first point of the axis of revolution.

• Angle of Revolution

• Sets the endpoint for the axis of revolution.

• Axis Endpoint

• Specifies how far the selected object revolves about the axis.

Match the following misconceptions with their answers:

• My object isn't solid after revolving

• Drawing a center axis ensures precision.

• Can I revolve an object only halfway?
