CAD中存在的道路线代表单线道路，单线道路跟当前绘制的双线道路发生关系，以该类记录：
|
|||
|
|
单线道路跟当前道路的关系有以下：
|
|||
|
|
1、单线道路只能跟道路的一侧相交，如果某道路交与两侧，则需要拆改道路为两个interStruct;
|
|||
|
|
2、当先道路相对于当前道路有以下位置：起点外，终点外，道路内。（EPointAtRoad m_eAtRoad;）
|
|||
|
|
3、根据交点与自身的关系，单线道路分为这两种情况，交点在单线上，交点在单线延长线上。(BOOL m_bInEdge;)
|
|||
|
|
4、需要记录单线是哪一端跟道路发生相交(BOOL m_bStart)
|
|||
|
|
5、单线道路跟当前道路在同一侧可能会产生两个交点，此时实际上存在两个不同的itnerStruct;
|
|||
|
|
为了防止生成单线道路的时候，重复，需要设置attach的标记，防止处理的重复。
|
|||
|
|
{BOOL m_bAttached; CInterStruct *m_pInterStructAttached;}
|
|||
|
|
6、单线道路肯定存在一个关联CAD中的单线，新的单线被处理之后，旧的要被删除掉。

|||

// CAD中道路单线跟当前双线道路发生相交之后，根据交点对该单线执行拆分：

|
// 1、拆分出来的单线在道路内部
|
|||
|
|
// 2、拆分出来的单线跟当前道路没关系 （没有相交）
|
