如何 BlockReference 对象属性

Question

问题是 BlockReference 对象上的字段 DEPT_NAME 未获取值。如何获取值

我尝试了给定的代码但没有得到任何结果

wb = copy(xl_workbook)

        acad = Autocad()
        print(cwd)
        acad.app.Documents.open(cwd + "/" + f)

        print(acad.doc.Name)

        num_cols = xl_sheet.ncols  # Number of columns
        idx = 1

        acad = win32com.client.Dispatch("AutoCAD.Application")

        doc = acad.ActiveDocument  # Document object

        print("MODEL SPACE")
        count=0
        for entity in acad.ActiveDocument.ModelSpace:
            name = entity.EntityName
            print(name)
            if name == 'AcDbBlockReference':
                HasAttributes = entity.HasAttributes
                if HasAttributes:
                    # sheet.row(idx).write(0, entity.TextString)
                    sheet.row(idx).write(1, entity.ObjectID)
                    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追溯（最近一次通话）：文件 "auto1.py"，第 78 行，位于打印（attrib.DEPT_NAME）文件 "D:\autocad_test\venv\lib\site-packages\win32com\client\dynamic.py"，第 527 行，在 getattr 中提高 AttributeError("%s.%s" % (self.username, attr)) 属性错误：GetAttributes.DEPT_NAME

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TagString 属性属性，如果它与您的目标属性匹配，则输出属性的 TextString 属性。

我猜您需要以下内容：

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