The Sweep tool is similar
to the extrude tool in that it can turn a 2D object into 3D by giving it
height. The sweep tool is much more versatile though, because you
can sweep along arcs and splines or lines that are angled. This
gives you much more flexibility than a simple extrusion, which can only
be done straight at a 90 degree angle.
To use the Sweep tool,
first select which items you want to sweep in order to create the new
object. These items will be the "cross-section" of the object
after the Sweep command is done. After you have selected
everything, choose the line along which you want to create the Sweep.
