NOTE Select face and edge subobjects by pressing Ctrl while you select them.
The path should not lie on the same plane as the object, nor should the path
have areas of high curvature.
The extrusion starts from the plane of the object and maintains its orientation
relative to the path.
If the path contains segments that are not tangent, the program extrudes the
object along each segment and then miters the joint along the plane bisecting
the angle formed by the segments. If the path is closed, the object should lie
on the miter plane. This allows the start and end sections of the solid to match
up. If the object is not on the miter plane, the object is rotated until it is on
the miter plane.
Objects with multiple loops are extruded so that all of the loops appear on
the same plane at the end section of the extruded solid.
Taper angle Specifies the taper angler for the extrusion.
Positive angles taper in from the base object. Negative angles taper out. The
default angle, 0, extrudes a 2D object perpendicular to its 2D plane. All selected
objects and loops are tapered to the same value.
Specifying a large taper angle or a long extrusion height can cause the object
or portions of the object to taper to a point before reaching the extrusion
height.
Individual loops of a region are always extruded to the same height.
