Deleting the Curves that Generate the Solid or Surface
The DELOBJ system variable controls whether the curves that generate an
object are automatically deleted after the solid or surface is created. However,
if surface associativity is on, the DELOBJ setting is ignored and the generating
curves are not deleted.
Create a Solid or Surface by Extruding
Create a 3D solid or surface by stretching curves into 3D space.
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 446.
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.
