pyautocad需要运行autoCad软件吗？

Question

我收到了一个错误。当我尝试将dwg AutoCAD文件转换为excel时。我用过http://www.run8tech.com/script-to-update-text-and-mtext-in-autocad-from-excel.aspx我收到了一个错误

这是我跑的剧本。运行autocad是否需要使用此库pyautocad

from __future__ import print_function

#Create workbook
book = xlwt.Workbook()
ws = book.add_sheet("ExportedData")
book.save("Exported.xls")

#Open the workbook
xl_workbook = xlrd.open_workbook("Exported.xls")
sheet_names = xl_workbook.sheet_names()

xl_sheet = xl_workbook.sheet_by_name(sheet_names[0])

wb = copy(xl_workbook)
sheet = wb.get_sheet(0)

dwgfiles = filter(os.path.isfile, os.listdir( os.curdir ) )

      acad = Autocad()
      print(cwd)

      print (acad.doc.Name)

                      idx = idx + 1



      doc.Close(False)
      acad = None
wb.save("Exported.xls")

当我运行此脚本错误时，我得到的是这个

  acad.doc.Open(cwd + "/" + f)

Answer 1

你会得到错误：

OSError：[WinError -2147221005]无效的类字符串

如果

1. 您没有安装AutoCAD
2. 如果您安装了某个版本，但是在安装AutoCAD20时尝试实例化错误的版本，例如：CreateObject("Autocad19.Application")。

通常，库会保留版本号，因此“Autocad.Application”可以正常工作。

如果安装了对Autocad()的调用将启动AutoCAD实例。
