Creating solids and surfaces by revolution

When we need a solid or surface whose section is rotated around an axis, the next command should be applied.

The REVOLVE command

The REVOLVE command (alias REV) creates a solid or surface by rotating a linear or planar object around an axis. It starts by showing the same information and prompts for the selection of sections, as seen with EXTRUDE. We can select any planar object. If an object is not closed or if the MOde option is set to Surface, a surface is created:

Command:  REVOLVE
Current wire frame density:  ISOLINES=4, Closed profiles creation mode = Solid
Select objects to revolve or [MOde]: Selection

We must then define the axis of revolution. By default, we can pick two points that define this axis, but other options are available as well. In the order we select, the points specify the positive angle direction by the right-hand rule.

Specify axis start point or define axis by [Object/X/Y/Z] <Object>: Point
Specify axis endpoint: Point...
