例

VBA:

Sub Example_PurgeFitData()
    ' This example creates a spline object in model space.
    ' It then returns the current number of fit points,
    ' and then purges the fit data.

    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) = 0: fitPoints(1) = 0: 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
    
    MsgBox "Before the purge there are " & splineObj.NumberOfFitPoints & " fit points.", , "PurgeFitData Example"

    ' Purge the fit data
    splineObj.PurgeFitData

    ThisDrawing.Regen True
    MsgBox "After the purge there are " & splineObj.NumberOfFitPoints & " fit points.", , "PurgeFitData Example"
