IAddProfileBsplineDLL Method (IBody2)

Adds a profile B-spline.

.NET Syntax

Visual Basic (Declaration) 
Function IAddProfileBsplineDLL( _
   ByRef Properties As System.Integer, _
   ByRef KnotArray As System.Double, _
   ByRef ControlPointCoordArray As System.Double _
) As Curve
Visual Basic (Usage) 
Dim instance As IBody2
Dim Properties As System.Integer
Dim KnotArray As System.Double
Dim ControlPointCoordArray As System.Double
Dim value As Curve
value = instance.IAddProfileBsplineDLL(Properties, KnotArray, ControlPointCoordArray)
Curve IAddProfileBsplineDLL( 
   ref System.int Properties,
   ref System.double KnotArray,
   ref System.double ControlPointCoordArray
Curve^ IAddProfileBsplineDLL( 
&   System.int% Properties,
&   System.double% KnotArray,
&   System.double% ControlPointCoordArray


Contains 4 longs (see Remarks)
Pointer to an array of numKnots doubles (see Remarks)
Pointer to an array of numCtrlPtCoord doubles (see Remarks)

Return Value

Pointer to the profile B-spline curve


You can use this method with IBody2::ICreateRevolutionSurface to generate any surface
of revolution or with IBody2::ICreateExtrusionSurface to generate a tabulated cylinder.

The Properties argument contains the following values:

  • DimensionControlPoints
  • Order
  • NumCtrlPoints
  • Periodicity

The length of the KnotArray argument is:

numKnots = NumCtrlPoints + Order

The length of the ControlPointCoordArray is:

numCtrlPtCoord = NumCtrlPoints * DimensionControlPoints
