### 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。
