                                                    If your curve can be created in a 2D Workplane (which is usually the best way, when possible to do), you can revolve that curve into a 3D space.  Note that such a revolved curve will form a surface, not a solid.  If you want to form a volume (aka, solid) in 3D, you should probably revolve a 2D surface from a workplane.
If your proposed curve (or surface) cannot be contained/represented in a flat plane, then I do not believe there is a straightforward way to revolve it into a 3D surface (or volume). But you may be able to use it to assist you in constructing the 3D volume of interest to you, if combined with other means (such as extrude, sweep, loft, etc.)  There are many ways to actually construct 3D surfaces and/or volumes.  So if you have a particular shape that you are trying to make, you might want to describe it in more detail here, since other users may have helpful suggestions to offer.
