While working within AutoCAD, users can see layout improvements instantly as well as be able to quantify how much money is being wasted on material handling by moving parts around the factory. Using an AutoCAD layout and an Excel routing file, engineers can see how lean their factory can be. Straight-line material flow diagrams show you what equipment and which areas of the layout are linked together by part flow. The aisle-based flow diagrams give you a more accurate calculation of part distance traveled, material handling times and costs.
