The EXTRUDE command creates a solid or surface that extends the shape of
a curve. Open curves create surfaces and closed curves create solids or surfaces.
See
Overview of Creating Solids and Surfaces on page 966.
Options for Extrusion
When you extrude objects, you can specify any of the following options:
Mode. Sets whether the extrude creates a surface or a solid.
Specify a path for extrusion. With the Path option, create a solid or surface
by specifying an object to be the path for the profile, or shape, of the
extrusion. The extruded object starts from the plane of the profile and
ends on a plane perpendicular to the path at the endpoint of the path. For
best results, use object snaps to make sure that the path is on or within
the boundary of the object being extruded.
Extruding is different from sweeping. When you extrude a profile along a
path, the profile follows the shape of the path, even if the path does not
intersect the profile. Sweeping usually provides greater control and better
results.
