如何计算两条线段的交点AcGeLineSeg3d

admin

1. AcGeLineSeg3d acGeLineSegtmp1(AcGePoint3d(0,100,0),AcGePoint3d(50,100,0));
2. AcGeLineSeg3d acGeLineSegtmp2(AcGePoint3d(-50,50,0),AcGePoint3d(-50,120,0));
3. AcGeTol gGetol;gGetol.setEqualPoint(0.001);//设置精度
4. AcGePoint3d intPnt;//交点
5. bool bRec = acGeLineSegtmp1.intersectWith(acGeLineSegtmp2,intPnt,gGetol);//交点
