About Creating 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.
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.
- Taper angle. Tapering the extrusion is useful for defining part that require a specific taper
angle, such as a mold used to create metal products in a foundry.
- Direction. With the Direction option, you can specify two points to set the length and direction
of the extrusion.
- Expression. Enter a mathematical expression to constrain the height of the extrusion.
