Get BCurve Spline Points Example (VBA)

This example shows how to get B-spline parameter data (knots, control points, etc.) for a selected spline
or curve.

'---------------------------------------------------------------------------
' Preconditions:
' 1. Open public_documents\samples\tutorial\molds\telephone.sldprt.
' 2. Select a curve.
' 3. Open the Immediate Window.
'
' Postconditions: Examine the Immediate window.

    Dim swSelectMgr As SldWorks.SelectionMgr
    Set swSelectMgr = Part.SelectionManager

    Dim swSketchSeg As SldWorks.Edge
    Set swSketchSeg = swSelectMgr.GetSelectedObject6(1, -1)

    Dim swCurveIn As SldWorks.Curve
    Dim swSplineParaData As SldWorks.SplineParamData
   
    Dim boolStatus As Boolean
    Dim i As Long
  

    Set swCurveIn = swSketchSeg.GetCurve
