Direction Specifies the length and direction of the extrusion. (The direction
cannot be parallel to the plane of the sweep curve created by the extrusion.)
■ Start point of direction. Specifies the first point in the direction vector.
■ End point of direction. Specifies the second point in the direction vector.
Path Specifies an object, such as a line or spline, that determines the path
and length of the extrusion. The outline of the mesh face is swept along the
path. The new orientation of the swept mesh face is perpendicular to the
endpoint of the path.
The path should not lie on the same plane as the mesh face or have areas of
high curvature. For extrusions that adhere closely to the curved path, use a
spline, not an arced polyline, as the path.
Taper angle Sets an angle of taper for an extrusion.
Positive angles taper inward from the base mesh face. Negative angles taper
outward. The default angle, 0, extrudes the face perpendicular to the plane of
the mesh.
If the adjacent faces are not set to be joined, the faces that are selected for
extrusion are tapered to the same value. However, for joined extrusions, the
taper is applied only to the portion of the extrusion that is not adjacent to
another extruded face.
