好的，我是VBA的新手，也是第一次来这里。 这是我的情况，我有一个代表调查点的x，y，z坐标列表。 在列表中，每组坐标都有一个分配的特征代码。 只有两个不同的（200 =地面点）和（311 =极点基点）。 我基本上需要找到极点座标，然后找到极点半径为6英尺的所有地面点，然后将其放在新的图纸上，在这里我可以进行进一步的计算，例如确定极点基点和地面点之间的z值。 导入以下表格后，请参阅以下屏幕截图，以获取调查数据的外观。

我编写了一部分代码，通过寻找极点特征代码“ 311”来找到极点编号和坐标，然后将其粘贴到新的工作表上，但是我似乎无法弄清楚如何编写代码来找到地面点位于杆的6英尺半径内。 我知道我可以使用距离公式“ = sqrt（（a2-a1）^ 2 +（b2-b1）^ 2）”只是不确定如何编码。 任何帮助将不胜感激。

这是我的代码的第一部分：

Sub embed_slope()
'
'
Dim P As Integer
Dim px As Long
Dim py As Long
Dim pz As Long
Dim gx As Long
Dim gy As Long
Dim gz As Long
P = 311
    For Row1 = 2 To 50
        For Row = 2 To 50
            Cells(Row, 3).Select                'search for pole feature code
            If Selection.Value = "" Then Exit For
            If Selection.Value = "311" Then
                ActiveCell.Offset(0, 8).Select      'copy pole number
                Selection.Copy
                Sheets("Data").Select
                Cells(Row1, 1).Select
                ActiveSheet.Paste                   'paste pole number on data sheet
                Sheets("Survey Input").Select
                Application.CutCopyMode = False
                ActiveCell.Offset(0, -7).Select     'copy coorinates
                Range(ActiveCell, ActiveCell.Offset(0, 2)).Copy
                Sheets("Data").Select
                Cells(Row1, 2).Select
                ActiveSheet.Paste
                Sheets("Survey Input").Select
                Application.CutCopyMode = False
            End If
        Next Row
    Next Row1
End Sub

我不确定您需要做什么，但是在分析了代码之后，我猜测您想要下面的代码。 该过程将查找极点基点并将其数据复制到Data表中，然后搜索与每个极点基点相距6英尺的所有接地点，并将其数据复制到Data表中。 我使用函数fnDistance计算点之间的距离。
