dxf格式中Entities段中lwpolyline中的组码70代表什么？

看了帮助也还是不太懂，


我的dxf文件中组码70后出现了129可帮助文档里没有这个值呀？

好像是顶点数吧

0表示不闭合，1表示闭合。

Vertex flags:
1 = Extra vertex created by curve-fitting
2 = Curve-fit tangent defined for this vertex. A curve-fit tangent direction of 0 may be omitted from DXF output but is significant if this bit is set
4 = Not used
8 = Spline vertex created by spline-fitting
16 = Spline frame control point
32 = 3D polyline vertex
64 = 3D polygon mesh
128 = Polyface mesh vertex
129=1+128
