改造说明

1. b3d控制长度计算模式：
   • b3d=true：使用三维空间距离（X,Y,Z全部参与计算）
   • b3d=false：只算二维平面距离（忽略Z坐标，投影到XY平面）
2. 增加Polyline（轻多义线，AcDbPolyline）支持，轻多义线是CAD常用多段线，注意区分：
   • Polyline= 轻多义线（ObjectClass.DxfName == “LWPOLYLINE”）✅ 本次支持
   • Polyline2d= 老式2D多段线（DxfName:“POLYLINE”，老图才会有，可选加）
3. 原有Line逻辑保留，统一提取长度方法，减少重复代码。

重点：轻多义线的每一段都要累加长度；并且同样支持2D/3D模式。轻多义线本身顶点自带Z值，2D模式下计算时把Z置0。
