BSplineWrapMode Enumeration
B-spline curve and surface types in this library are non-periodic. But they can be created from legacy periodic data.
This enumeration lists the possible ways a B-spline object can have been created from legacy periodic data.

No conversion performed. | 
| OpenByAddingControlPoints | 
 | 
The B-spline was opened up by adding degree wrap-around control points to the legacy periodic data. * This is typical of B-splines constructed with maximum (degree - 1) continuity. * Knots are unaffected by this conversion. | 
| OpenByRemovingKnots | 
 | 
The B-spline was opened up by removing degree extreme knots from the legacy periodic data. * This is typical of rational B-spline curves representing full circles and ellipses. * Poles are unaffected by this conversion. |
