Returns the order in the u and v directions, respectively.
Returns the number of poles in the u and v directions, respectively.
Returns the number of knots in the u and v directions, respectively.
Returns True if the surface is rational (that is, a weight is assigned to every pole).
Returns True as the first element if the surface is closed in the u direction. Returns True as the second element if the surface is closed in the v direction.
Returns True as the first element if the surface is periodic in the u direction. Returns True as the second element if the surface is periodic in the v direction.
Returns True if the surface is considered planar.
Description
Returns the overall information related to the referenced B-Spline object.

Parameters
Order
Returns the order in the u and v directions, respectively.
NumPoles
Returns the number of poles in the u and v directions, respectively.
NumKnots
Returns the number of knots in the u and v directions, respectively.
Rational
Returns True if the surface is rational (that is, a weight is assigned to every pole).
Closed
Returns True as the first element if the surface is closed in the u direction. Returns True as the second element if the surface is closed in the v direction.
Periodic
Returns True as the first element if the surface is periodic in the u direction. Returns True as the second element if the surface is periodic in the v direction.
Planar
Returns True if the surface is considered planar.
Remarks
Use this method to determine the amount of memory needed to obtain the variable length information that fully defines the object.
