摘要
论述了数字地面模型（ＤＴＭ）在公路路线ＣＡＤ的实用技术，介绍了在Ａｕｔｏ－ＣＡＤ图形环境下，交互式形成三角网ＤＴＭ的原理与方法，以及如何通过ＤＴＭ生成三维地面和纵、横地面线。
Based on the principles and the applied techniques, an optimized method to create triangle digital terrain model (DTM) graphically and dynamically on the AutoCAD graphics environment is presented. By evaluating the formed DTM, the profile and the cross section information can be generated for the use of further geometric designs, and the 3D terrain can also be displayed on the screen as design background to check the reality of the original topography. Therefore, the quality and efficiency of highway alignment design can be greatly improved.
