Create a Solid or Surface by Revolving
Concept Procedure Quick Reference
 
 
 

With the REVOLVE command, you can create a solid or surface by revolving open or closed objects about an axis. The revolved objects define the profile of the solid or surface.

If you revolve a closed object, the result is a solid. If you revolve an open object, the result is a surface.

You can revolve more than one object at a time.

When you revolve objects, you can specify any of the following as the axis about which to revolve the objects:

You can use the following objects when you use REVOLVE:

NoteYou can select faces on solids or surfaces by pressing and holding CTRL, and then selecting one or more faces.

If you want to create a solid using a profile made up of lines or arcs that meet a polyline, use the PEDIT Join option to convert them to a single polyline object before you use REVOLVE. If you don’t convert these objects to a single polyline, a surface will be created when you revolve them.

You cannot use REVOLVE on objects contained within a block or polylines that have crossing or intersecting segments.
