Contemporary CAD systems are capable of generating, and realistic-looking three-dimensional graphic designs that can be rotated and viewed from all sides. Troy Lee Designs, which makes sports helmets, recently invested in CAD software that could create the helmets in 3-D. The technology defined the shapes better than traditional methods, which involved sketching an idea on paper, hand-molding a clay model, and shipping the model to Asia factories to create a plastic prototype. Production is now about six months faster and about 35 percent cheaper, with Asian factories able to produce an exact replica after receiving the digital design via e-mail (Maltby,2010).
