P
DegreeU
|
int
|
The degree of the spline in the u-direction.
|
|
P
DegreeV
|
int
|
The degree of the spline in the v-direction.
|
|
P
IsRational
|
bool
|
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.
|
|
P
IsValidObject
|
Boolean
|
Specifies whether the .NET object represents a valid Revit entity.
|
|
P
ReverseOrientation
|
bool
|
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.
