例

VBA:

Sub Example_GetFitPoint()
    ' This example creates a spline object in model space.
    ' It then finds the coordinates of the fit points.

    ' Create the spline
    Dim splineObj As AcadSpline
    Dim startTan(0 To 2) As Double
    Dim endTan(0 To 2) As Double
    Dim fitPoints(0 To 8) As Double
    
    startTan(0) = 0.5: startTan(1) = 0.5: startTan(2) = 0
    endTan(0) = 0.5: endTan(1) = 0.5: endTan(2) = 0
    fitPoints(0) = 1: fitPoints(1) = 1: fitPoints(2) = 0
    fitPoints(3) = 5: fitPoints(4) = 5: fitPoints(5) = 0
    fitPoints(6) = 10: fitPoints(7) = 0: fitPoints(8) = 0
    Set splineObj = ThisDrawing.ModelSpace.AddSpline(fitPoints, startTan, endTan)
    ZoomAll
    
    ' Display the coordinates of the fit points
    Dim fitPoint As Variant
    Dim index As Integer
    For index = 0 To splineObj.NumberOfFitPoints - 1
        fitPoint = splineObj.GetFitPoint(index)
        MsgBox "Fit point " & index + 1 & " is at " & fitPoint(0) & ", " & fitPoint(1) & ", " & fitPoint(2), , "GetFitPoint Example"
    Next
    
End Sub
