NurbSurfaceInsertKnotAtV Method

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

Assembly: TD_Mgd (in TD_Mgd.dll) Version: 24.2.0.0

Syntax

C++

Copy

public void InsertKnotAtV(
        double dV
)

Public Sub InsertKnotAtV ( 
        dV As Double
)

public:
void InsertKnotAtV(
        double dV
)

member InsertKnotAtV : 
        dV : float -> unit

Parameters

dV Double: [in] V 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 v parameter is bigger than the degree in the v-direction, throws the eInvalidInput exception. If this method is not implemented for a specific modeler, throws the eNotImplementedYet exception.
