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
有時控制尺寸會有所調整，有時節點板設計會變化一下。傳統繪圖時，面對修改，面對審圖人員發現的錯誤，繪圖人員往往只能夠手工一筆一劃地修改dwg圖形，工作量非常大。雖然有自動成圖軟體的支持，但是對待修改圖的工作，依賴自動成圖軟體重新從頭再生成一遍圖形既麻煩又可能帶來其它意想不到的問題。 -
