写一段CAD vba代码，将某工作表中的A列和B列中的值为空间中的点的横坐标和纵坐标，用逗号进行连接，将每个点用线段连接起来，并求每条直线与水平轴的夹角弧度

### 回答1：

Sub CAD_VBA()
Dim ws As Worksheet
Set ws = ThisWorkbook.Sheets("Sheet1")
Dim lastrow As Integer
lastrow = ws.Cells(Rows.Count, 1).End(xlUp).Row
Dim i As Integer
Dim pointString As String
pointString = ""
For i = 2 To lastrow
pointString = pointString & ws.Cells(i, 1).Value & "," & ws.Cells(i, 2).Value & ","
Next i
pointString = Left(pointString, Len(pointString) - 1)
Dim myLine As AcadLine
Set myLine = ThisDrawing.ModelSpace.AddLine(pointString)
myLine.Layer = "MyLayer"
Dim angleRad As Double
angleRad = myLine.Angle
MsgBox "每条直线与水平轴的夹角弧度为：" & angleRad
End Sub

### 回答2：
以下是一个简单的CAD VBA代码，实现了您描述的功能：

Sub DrawLinesAndCalculateAngles()
Dim i As Integer
Dim lastRow As Integer
Dim startPoint As Variant
Dim endPoint As Variant
Dim angle As Double

' 获取当前工作表的最后一行
lastRow = Sheets("Sheet1").Cells(Rows.Count, 1).End(xlUp).Row

' 循环处理每个点
For i = 2 To lastRow
startPoint = Sheets("Sheet1").Cells(i, 1).Value
endPoint = Sheets("Sheet1").Cells(i, 2).Value

' 在CAD中画线段连接两个点
ThisDrawing.ModelSpace.AddLine startPoint, endPoint

' 计算每条直线与水平轴的夹角弧度
angle = Math.Atan((endPoint(1) - startPoint(1)) / (endPoint(0) - startPoint(0)))

' 输出每条直线的夹角
Sheets("Sheet1").Cells(i, 3).Value = angle
Next i
End Sub

这段代码假设要处理的数据来自工作表"Sheet1"，点的横坐标存储在A列，纵坐标存储在B列。代码根据点的坐标在CAD中画出线段，并计算每条直线与水平轴的夹角弧度，并将结果写入C列。

下面是一个用VBA编写的CAD代码示例，用于将某个工作表中的A列和B列中的值作为点的横坐标和纵坐标，并将每个点用线段连接起来，并计算每条直线与水平轴的夹角弧度。

Sub DrawLinesAndComputeAngles()

    Dim objApp As AcadApplication
    Dim objDoc As AcadDocument
    Dim objModelSpace As AcadModelSpace
    Dim objLine As AcadLine
    
    Dim ws As Worksheet
    Dim lastRow As Long
    Dim i As Long
    Dim x As Double
    Dim y As Double
    Dim angle As Double
    
    ' 获取当前运行的CAD应用程序
    Set objApp = GetObject(, "AutoCAD.Application")
    
    ' 获取当前的文档
    Set objDoc = objApp.ActiveDocument
    
    ' 获取模型空间
    Set objModelSpace = objDoc.ModelSpace
    
    ' 打开Excel工作簿
    Set ws = ThisWorkbook.Sheets("Sheet1")
    
    ' 获取A列和B列最后一行的行号
    lastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row
    
    ' 逐行处理A列和B列的值
    For i = 1 To lastRow
        ' 获取横坐标和纵坐标的值
        x = ws.Cells(i, "A").Value
        y = ws.Cells(i, "B").Value
        
        ' 在CAD中创建点对象，并设置其坐标
        objModelSpace.AddPoint (x, y)
        
        ' 连接相邻两个点，形成直线
        If i > 1 Then
            Set objLine = objModelSpace.AddLine(Array(ws.Cells(i - 1, "A").Value, ws.Cells(i - 1, "B").Value, 0), Array(x, y, 0))
            
            ' 计算直线与水平轴的夹角弧度
            angle = WorksheetFunction.Atan2(objLine.StartPoint(1) - objLine.EndPoint(1), objLine.StartPoint(0) - objLine.EndPoint(0))
            Debug.Print "Line " & i - 1 & " angle: " & angle
        End If
    Next i
    
    ' 更新CAD图形显示
    objDoc.Regen acAllViewports
    objApp.ZoomExtents

End Sub

请确保在运行该代码之前已经在CAD中打开了一个文档，并且在Excel工作簿的"Sheet1"工作表中有数据。代码将逐行读取A列和B列的值，并在CAD中创建对应的点对象，然后用线段连接相邻两个点。并计算每条直线与水平轴的夹角弧度，并在VBA中输出结果（通过调试输出）。

请注意，该代码使用了Excel VBA与CAD的COM接口进行交互，因此在运行代码之前，需要确保已经正确安装了CAD，并且在Excel中启用了对应的CAD的COM插件。
