问题是 BlockReference 对象上的字段 DEPT_NAME 没有获取值。 如何获取价值

我尝试了给定的代码,但没有得到任何结果

            print(name)
            if name == 'AcDbBlockReference':

                    sheet.row(idx).write(2, cwd + "/" + f)
                    sheet.row(idx).write(3, str(entity.InsertionPoint))
                    sheet.row(idx).write(4, entity.Name)
                    sheet.row(idx).write(5,entity.Layer)
                    idx = idx + 1
                    print(entity.Name)
                    print(entity.Layer)
                    print(entity.ObjectID)
                    k=0

                    #print(entity.get_attrib_text('DEPT_NAME'))

                    for attrib in entity.GetAttributes():
                        print(attrib.DEPT_NAME)
                        print("+++++++")
                    exit()



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

我得到的错误是这个 回溯(最近一次通话最后): 文件“auto1.py”,第 78 行,在 打印(attrib.DEPT_NAME) getattr 中的文件“D:\autocad_test\venv\lib\site-packages\win32com\client\dynamic.py”,第 527 行 raise AttributeError("%s.%s" % (self.username, attr)) AttributeError: GetAttributes.DEPT_NAME

    【解决方案1】:

    假设此 Python 插件的实现与 AutoCAD ActiveX 对象模型的属性和方法一致,那么您需要查询属性的 TagString 属性,如果它与您的目标属性匹配,则输出TextString 属性的属性。

    我猜你会需要一些类似以下的东西:

    for attrib in entity.GetAttributes():
        if attrib.TagString == 'DEPT_NAME':
            print(attrib.TextString)
            print("+++++++")
    exit()
