6.7.11 NURBSUBC (r, c)
Creates a nurbs curve defined by a subrange r of the parametric domain
of another nurbs curve c.
r is a typeless node to which the lower and upper bound of the
subrange of the parametric domain of the other curve are connected,
c must be of type NURBCURV (see 6.7.9).
In the C++ class hierarchy the class created by the NURBSUBC keyword is derived
from a general nurbs curve class (see NURBCURV, 6.7.9),
so that it can be used at any places where a nurbs curve is expected
(with the same number format and control point type of course)
The following variations of this keyword exist (some of them
define the same internal structures, and are only defined to allow
consistent naming conventions):
