Using Control Points
By default, each cross section consists of four control points. You can use these
control points to alter the shape of a single cross section. The control points
define the shape (perimeter) of the section. Moving one point affects the shape
between itself and its neighbors on each side.
Rotating and Scaling
Control points are internally positioned using cylindrical coordinates, that is
a distance from the link at some angle around the link. To move a control
point, you must scale it to the correct distance from the link and then rotate
it into the orientation you desire. The move tool actually serves the dual
function of rotating and scaling at the same time.
