NurbSurfaceInsertKnotAtU Method

Inserts a knot at the specified u parameter. The knot insertion doesn't modify the shape of the surface. It adds a new row of control points in the v-direction and adjusts the local control point's location.

Syntax

C++

Copy

public void InsertKnotAtU(
        double dU
)

Public Sub InsertKnotAtU ( 
        dU As Double
)

public:
void InsertKnotAtU(
        double dU
)

member InsertKnotAtU : 
        dU : float -> unit

Parameters

dU Double: [in] U parameter.

Remarks

If the surface doesn't contain any NURBS information, the method throws the eFail exception. If the surface's knot multiplicity at the u parameter is bigger than the degree in the u-direction, throws the eInvalidInput exception. If this method is not implemented for a specific modeler, throws the eNotImplementedYet exception.
