Question

我正在使用 ezdxf软件包以写入dxf文件。我需要帮助存储折线的属性信息。为什么不能在布局/模型空间上使用add_attrib函数？下面是代码； dataObj是一个geojson字符串：

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'])

我收到的错误是：

ezdxf.lldxf.const.DXFValueError: 2 or 3 axis required

如何使用ezdxf向折线添加属性信息？
