Design Software Comes with Machine Shop Attached

"It's the Internet Revolution meets the Industrial Revolution: a new program that lets people design 3-D objects like car parts and door knobs in metal or plastic then order them online. Programs for computer-aided design, or CAD, have been around for decades, but eMachineShop.com appears to be the first service that checks whether a design can be made, tells the customer how much it will cost. If the customer wants the item the design goes to a "real world" machine shop for manufacturing."
