2024-5-18 18:32| 发布者: admin| 查看: 79| 评论: 0|原作者: admin|来自: AutoCAD

将拟合点添加到给定索引处的样条曲线。

支持的平台：仅限 Windows

签名

VBA：

object.AddFitPoint Index, FitPoint

对象

类型：样条曲线

此方法应用到的对象。

指数

访问：仅输入

类型：整数

在拟合点列表中的位置以添加拟合点。如果索引为负数，则该点将添加到样条曲线的开头。如果索引超过样条曲线中的拟合点数，则该点将添加到样条曲线的末端。

FitPoint的

访问：仅输入

类型：变体（双打的三元素阵列）

指定要添加的拟合点的 3D WCS 坐标。

返回值（RetVal）

无返回值。

言论

AutoCAD 将添加该点，并在新点集中重新调整样条。若要查看更改，请使用 or 方法。UpdateRegen

例子

VBA：

Sub Example_AddFitPoint()
    ' This example creates a spline object in model space.
    ' It then adds a fit point to the spline.

    ' 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
    
    ' Create the spline object
    Set splineObj = ThisDrawing.ModelSpace.AddSpline(fitPoints, startTan, endTan)
    ZoomAll
    MsgBox "The Spline has " & splineObj.NumberOfFitPoints & " fit points.", , "AddFitPoint Example"
    
    ' Define the new fit point
    Dim newFitPoint(0 To 2) As Double
    newFitPoint(0) = 8: newFitPoint(1) = 5: newFitPoint(2) = 0
    
    ' Add the new fit point at the first index in the spline's array of points
    splineObj.AddFitPoint 1, newFitPoint
    ThisDrawing.Regen True
    MsgBox "A fit point has been added at Index:1  WCS: 8, 5, 0" & vbCrLf & "The Spline has " & splineObj.NumberOfFitPoints & " fit points.", , "AddFitPoint Example"

End Sub
