When you design something, the key is to obtain from point A to B and also accomplish a job between. Designers in the past would develop items by hand. Their point A was an empty sheet of paper and their point B was a completed design sheet. For modern designers, factor A is likely a blank CAD data and also point B could in fact be point C, D, or F. Problems unavoidably occur in the layout process, partly as a result of our restricted viewpoint behind the computer screen.
