| Abstract: | The essay elaborates the three dimensional modeling method of median line adding the cross section,and then makes the laneway entities run-through by Boolean operations when they intersect.Proposing the concrete solutions as to the essential technology of the modeling process in three dimensional coordinates transformation of cross section,triangle grid production and Boolean operations between the laneway entities.Finally,it produces the final test result.The experiment confirms the feasibility of three dimensional modeling methods. |

| Keywords: | three-dimensional modeling laneway coordinates transformation Boolean operations |
