| NurbsSurfaceData Properties |
| NurbsSurfaceData Class See Also |
The NurbsSurfaceData type exposes the following members.
Properties
| Name | Description | |
|---|---|---|
 | DegreeU |
The degree of the spline in the u-direction.
|
| DegreeV |
The degree of the spline in the v-direction.
|
| IsRational |
Tells if the spline is rational or not.
If it is true (rational), then the NURBS is a piecewise rational polynomial function.
If it is false (non-rational), then the NURBS is a piecewise polynomial function.
|
| IsValidObject |
Specifies whether the .NET object represents a valid Revit entity.
|
| ReverseOrientation |
If true, the surface's orientation is opposite to the canonical parametric orientation, otherwise it is the same.
The canonical parametric orientation is a counter-clockwise sense of rotation in the uv-parameter plane.
Extrinsically, the oriented normal vector for the canonical parametric orientation points in the direction of
the cross product dS/du x dS/dv, which S(u, v) is the parameterized surface.
