About a Revolved Surface
Use the Revolve tool to create a surface by revolving a sketched section around a centerline.
Define the angle of the revolved surfaces using one of the following angle options:
Variable—Revolves a section from the sketching plane by a specified angle value.
Symmetric—Revolves a section on each side of the sketching plane by half of the specified angle value in each direction.
To Reference—Revolves a section to a selected point, plane, or surface.
A revolved surface can have open or closed ends. To create a closed volume from the revolved surface, select Capped Ends to create additional surfaces that close the ends of the feature.

The Capped Ends option requires a closed section.
