Dear Asim,

Open profiles create surfaces and closed profiles can create either a solid or a surface. The MOde option controls is a solid of surface is created. When creating a surface, SURFACEMODELINGMODE system variable controls if a procedural or NURBS surface is created.

Revolve path and profile curves can be:

• Open or closed
• Planar or non-planar
• Solid and surface edges
• A single object (to extrude multiple lines, convert them to a single object with the JOIN command)
• A single region (to extrude multiple regions, first convert them to a single object with the UNION command)

To automatically delete the profile, use the DELOBJ system variable. If associativity is on, the DELOBJ system variable is ignored and the originating geometry is not deleted.

You cannot revolve objects contained within a block or objects that will self-intersect. REVOLVE ignores the width of a polyline and revolves from the center of the path of the polyline.

The right-hand rule determines the positive direction of rotation.

Revolve can be used with an object made from P lines, Polygons, Circles, Ellipses, and Splines. Objects must have a closed path to be revolved.

In Command bar , give Revolve command (rev) then select object and then press enter specify first axis and then press enter and then specify end axis and then specify angle of rotation. 

Follow the above procedure to use the revolve. This command is used for revolving the face of the solid surface/object
