The shortcut for the 'revolve' command in AutoCAD is ___.

Arrange the following steps in the correct order to use the revolve command:

• Select the object to be revolved.

• Specify the Axis Endpoint.

• Specify the degrees.

• Specify the Axis Start Point.

• Type 'REV' or select the 'Revolve' Command

Match the following modifiers with their correct descriptions:

• Object, “O”

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

• Start Angle

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

• Angle of Revolution

• Specifies the objects to be revolved about an axis.

• Axis Start Point

• Specifies the first point of the axis of revolution.

• Axis Endpoint

• Sets the endpoint for the axis of revolution.

Match the following misconceptions with their answers:

• My object isn't solid after revolving

• Just enter 180 degrees during the command.

• Do I need a drawn center axis?

• Use 'undo revolve', then 'join' all lines together.

• Can I revolve an object only halfway?

• Ensure the axis doesn't intersect with the object.

• My object self-intersects.

• Drawing a center axis ensures precision.

• I can't get my object to revolve.

• Zoom into the line intersections.
