CAD坐标导出到EXCEL
3星 · 编辑精心推荐
实现这个功能需要使用CAD的API库和Excel的COM接口。以下是一个简单的实现步骤:
1. 在VB.NET项目中添加对AutoCAD的引用,可以使用COM接口或.NET API接口,这里以COM接口为例。
2. 创建一个Excel应用程序对象,并打开一个新的工作簿。
3. 遍历CAD所有图元,获取每个图元的逐点坐标信息,并将其写入Excel工作簿中。
以下是代码示例:
```
Dim acadApp As AcadApplication = New AcadApplication()
Dim acadDoc As AcadDocument = acadApp.ActiveDocument
Dim excelApp As Excel.Application = New Excel.Application()
Dim excelWorkbook As Excel.Workbook = excelApp.Workbooks.Add()
Dim excelWorksheet As Excel.Worksheet = excelWorkbook.Sheets(1)
Dim rowIndex As Integer = 1
For Each entity As AcadEntity In acadDoc.ModelSpace
If TypeOf entity Is AcadCurve Or TypeOf entity Is AcadSolid Then
Dim points As Object() = entity.Coordinates
For i As Integer = 0 To points.Length - 1 Step 3
excelWorksheet.Cells(rowIndex, 1).Value = entity.EntityName
excelWorksheet.Cells(rowIndex, 2).Value = points(i)
excelWorksheet.Cells(rowIndex, 3).Value = points(i + 1)
excelWorksheet.Cells(rowIndex, 4).Value = points(i + 2)
rowIndex += 1
Next
End If
Next
excelWorkbook.SaveAs("output.xlsx")
excelWorkbook.Close()
excelApp.Quit()
```
请注意,此示例代码仅适用于简单的CAD图元,对于复杂的图元可能需要更复杂的处理逻辑。同时,此代码也需要进行错误处理和资源释放等操作,以确保程序的正确性和稳定性。
