平交口立面設計，由於其設計過程復雜和計算麻煩，設計者很難以等高線等形式來準確地表達設計意圖，只能是稀疏地手工計算標注若干高程式控制制點，設計成果對施工的指導及約束作用遠不能滿足要求。At the heart of slcad is a sophisticated three - dimensional engineering model. this model includes the terrain, the structures and all the wires. the model can be viewed in plan profile sheets. the slcad model is much more than just a picture or cad drawing since slcad understands the relationship between these elements. when you drag a structure off the current alignment slcad will update wire positions. the effects of this structure move will be instantly visible in the plan profile sheet view. in slcad you concentrate on designing your line instead of wasting your time drafting
