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
有时控制尺寸会有所调整，有时节点板设计会变化一下。传统绘图时，面对修改，面对审图人员发现的错误，绘图人员往往只能够手工一笔一划地修改dwg图形，工作量非常大。虽然有自动成图软件的支持，但是对待修改图的工作，依赖自动成图软件重新从头再生成一遍图形既麻烦又可能带来其它意想不到的问题。
