如何BlockReference对象属性

Question

问题是BlockReference对象上的某个字段DEPT_NAME没有获取该值。如何获得价值

我尝试了给定的代码但没有得到任何结果

        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Traceback（最近一次调用最后一次）：文件“auto1.py”，第78行，打印（attrib.DEPT_NAME）文件“D：\ autocad_test \ venv \ lib \ site-packages \ win32com \ client \ dynamic.py“，第527行，getattr引发AttributeError（”％s。％s“％（self.username，attr））AttributeError：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，那么您需要查询属性的TagString属性，如果它与您的目标属性匹配，则输出属性的TextString属性。

我猜你需要的东西如下：

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