Examples

VBA:

Sub Example_Weights()
    ' This example creates a Spline object in model space and
    ' returns the weight vector for the new Spline

    Dim splineObj As AcadSpline
    Dim startTan(0 To 2) As Double, endTan(0 To 2) As Double
    Dim fitPoints(0 To 8) As Double
    Dim weightVector As Variant

    ' Define the Spline object

    fitPoints(6) = 10: fitPoints(7) = 0: fitPoints(8) = 0
    
    ' Create new Spline object
    Set splineObj = ThisDrawing.ModelSpace.AddSpline(fitPoints, startTan, endTan)
        
    ' Add weights to the Spline
