Solid Edge and Pro Engineer 3D designer programs are used for CAD. Many manufacturing issues are revealed by computer-aided designing before the production of the expensive specimen. For build-to-order items produced in small series, CAD bears a high importance even when only one or two pieces of components are manufactured and if one out of one is a scrap it means 100%!

In case of complicated items, the amount of time spent on designing also bears a high importance since unforeseeable problems turn out before the manufacturing and it could be corrected rapidly on a low cost, accordingly the time and money intended for designing will be paid-off later.
