Tapering the selected face with a positive angle tapers the face in, and a
negative angle tapers the face out. The default angle, 0, extrudes the face
perpendicular to its plane. All selected faces in the selection set are tapered
to the same value. If you specify a large taper angle or height, you can
cause the face to taper to a point before it reaches the extrusion height.
Path Sets a path for the extrusion path based on a specified line or curve. All
the profiles of the selected face are extruded along the chosen path to create
the extrusion.
■ Select an extrusion path.
Lines, circles, arcs, ellipses, elliptical arcs, polylines, or splines can be paths.
The path should not lie on the same plane as the face, nor should it have
areas of high curvature.
The extruded face starts from the plane of the profile and ends on a plane
perpendicular to the path at the path's endpoint. One of the endpoints of
