Sets a complete data description of the NurbsSurface. This is only available from scripted operators; if you use it on an object with some clusters and you change the topology the burden of updating the clusters is on the user. For non-scripted operators this property can only be set if the object has been frozen.

Parameter | Type | Description |
---|---|---|
ControlPoints | 3D Array |
The control points are stored in a 3-dimensional array. The array is 4 * Number V ControlPoints * Number U ControlPoints |
UKnots | Array of Doubles | An array of knot values in U direction. |
VKnots | Array of Doubles | An array of knot values in V direction. |
UClosed | Boolean | Specifies whether the nurbs surface is closed in U direction. |
VClosed | Boolean | Specifies whether the nurbs surface is closed in V direction. |
UDegree | Long | Degree of the nurbs surface in U direction. |
VDegree | Long | Degree of the nurbs surface in V direction. |
UParameterization | siKnotParameterization | The parameterization factor of the nurbs surface in U direction. |
VParameterization | siKnotParameterization | The parameterization factor of the nurbs surface in V direction. |
NurbsFormat | siNurbsFormat |
Specifies how the data is formatted. Default Value: siSINurbs |
