Once the conceptual design is approved - we spend hours in front of a computer trying to figure out the best way to build a project. It's a tedious process but it pays dividends in the long run. By digitizing the hand drawing into a cad file we are able to scrutinize the design, and begin engineering the final product. But nothing compares to getting fresh laser cut parts in along with full scale paper print outs. Its the first time you see the product to scale and its an awesome feeling. All the doubts and second guessing are behind you - and now, finally, you get to the fun part.
