错误提示是
LWPOLYLINE entity was discarded because of invalid vertex coordinates (-2E-6,37.7)
LWPOLYLINE entity was discarded because of invalid vertex coordinates (129.999998,37.7)
LWPOLYLINE entity was discarded because of invalid vertex coordinates (35.639998,22.64)
LWPOLYLINE entity was discarded because of invalid vertex coordinates (62.680001,23.74)
LWPOLYLINE entity was discarded because of invalid vertex coordinates (36.739998,49.88)
LWPOLYLINE entity was discarded because of invalid vertex coordinates (42.94,20.6)
。
。

我把dxf文件中的坐标改成小数点后2位也还是不行，报错类别一样的。
