例

VBA:

Sub Example_SetFitPoint()
    ' This example creates a spline object in model space.
    ' It then finds the coordinates of the first fit point
    ' and changes that value.

    ' 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 first fit point
    Dim fitPoint As Variant
    fitPoint = splineObj.GetFitPoint(0)
    MsgBox "Fit point 1 is at " & fitPoint(0) & ", " & fitPoint(1) & ", " & fitPoint(2), , "SetFitPoint Example"
    
    ' Change the coordinates of the first fit point
    fitPoint(0) = 0: fitPoint(1) = 3: fitPoint(2) = 0
    splineObj.SetFitPoint 0, fitPoint
    splineObj.Update
    MsgBox "Fit point 1 is now at " & fitPoint(0) & ", " & fitPoint(1) & ", " & fitPoint(2), , "SetFitPoint Example"
