A single span curve is created that has two Edit Points (one at either end)
and 4 CVs.
NOTE The part of a curve between two edit points is called a span. If a more
complex curve is created with many edit points, there will be many spans,
one between each pair of edit points. When a curve has more spans, it also
has more CVs. These extra CVs can be used to create a more complex shape.
You will now increase the number of CVs in this curve so you can create
the zig-zag profile of the sleeve.
5 In the Control Panel, the number of spans that make up the curve is
displayed.
