在SolidWorks VBA中,如果你想随机获取所选边界线上的三个点的坐标,你可以编写一段脚本,如下所示,假设我们已经有一个`SelectedEdges`数组存储了所有选中的边缘对象:
```vba
Sub GetRandomPoints()
Dim edge As PartEdge
Dim startPoint As Point3d
Dim midPoint As Point3d
Dim endPoint As Point3d
' 获取选中边界的第一个点作为起点
For Each edge In SelectedEdges(0).Edges
startPoint = edge.StartPoint
Exit For
Next edge
' 随机生成中间点
Dim randomRange As Double
randomRange = edge.Length / 3 ' 边界长度除以3作为随机范围
Dim rand As Double
rand = Rnd * randomRange ' 生成介于0到随机范围内的一数值
midPoint = startPoint + rand * edge.DirectionVector
' 结束点为边界终点
endPoint = edge.EndPoint
' 输出三点坐标
Debug.Print "Start Point: (" & startPoint.X & ", " & startPoint.Y & ", " & startPoint.Z & ")"
Debug.Print "Middle Point: (" & midPoint.X & ", " & midPoint.Y & ", " & midPoint.Z & ")"
Debug.Print "End Point: (" & endPoint.X & ", " & endPoint.Y & ", " & endPoint.Z & ")"
End Sub
```
这个脚本会选取选定边界的第一点作为起点,然后沿着边界方向随机选择一个中间点,并最终获取边界终点。注意,这只是一个基本示例,实际应用中可能需要处理边界为空、无合适中间点等异常情况。
