5.2 5.2 Spline interpolation (ASPLINE, BSPLINE, CSPLINE, BAUTO, BNAT,
BTAN)
Function
The spline interpolation function can be used to link series of points along smooth curves.
Splines can be applied, for example, to create curves using a sequence of digitized points.
There are several types of spline with different characteristics, each producing different
interpolation effects. In addition to selecting the spline type, the user can also manipulate a
range of different parameters. Several attempts are normally required to obtain the desired
pattern.

In programming a spline, you link a series of points along a curve. You can select one of
three spline types:
• A spline (akima spline)
• B spline (non-uniform, rational basis spline, NURBS)
• C spline (cubic spline)
