A spline is a smooth curve that passes through or near a given set of points.
The SPLINE command creates a type of curve known as a nonuniform rational
B-spline (NURBS). A NURBS curve produces a smooth curve between control
vertices or fit points. The spline on the left is drawn with fit points, and the
spline on the right is drawn with control vertices.
