The profile can be revolved through any angle measuring between
zero and 360 degrees around an axis. The axis of revolution can
be part of the profile or offset from it. The profile and axis
must be coplanar. The Revolve command is used to create features
having radial symmetry, such as stepped shafts, cylindrical
containers, or O-rings. Such features can define the overall
shape of a part (a base feature) or become details such as fins,
webs, or struts. Revolving around an axis on the sketch produces
solid features, such as disks, hubs, and beveled gear blanks.
Revolving around an axis that is offset from the sketch creates
solids with holes, such as washers, flasks, and conduits. When
you specify a sphere or torus in the Primitives panel, the
sketch creation and revolve process is automated. You can select
a start plane for the sketch, create the profile, and then
create a solid. The primitive shape creation commands create
full revolutions and do not create surfaces or partial
revolutions. Shape propagatio
