Как добавить информацию об атрибутах в полилинию, используя ezdxf?

/ 07 февраля 2019

Я использую пакет ezdxf для записи файлов dxf.Мне нужна помощь для хранения информации об атрибутах для полилиний.Почему я не могу использовать функцию add_attrib в макете / пространстве модели?Ниже приведен код;dataObj - это строка геоджона: 

dwg = ezdxf.new('R2010')
flag = dwg.blocks.new(name='FLAG')
msp = dwg.modelspace()

#add attribute definitions
x = 0.5
y = -1
for i in Attribs:
    property = i;
    flag.add_attdef(str(property), (x, y), {'height': 0.5, 'color': 3})
    y = y-1.5

for i in range(numFeats):
    msp.add_polyline3d(dataObj[u'features'][i][u'geometry'][u'coordinates'])
    att_info_dict = dataObj[u'features'][i][u'properties']
    print dataObj[u'features'][i][u'geometry'][u'coordinates']
    print att_info_dict
    msp.add_attrib('DIAMETER',99,dataObj[u'features'][i][u'geometry'][u'coordinates'])

Я получаю ошибку:
