The user has no way of knowing if an answer returned by a calculator is correct or an error. The explanation I got for requiring the use of a slide rule was that the user had to know what the approximate answer would be, and would intuitively know if the slide rule solution was correct. I have designed many projects on the back of a napkin. ![]() ![]() One never knows when you may need to create something on the fly away from a computer or plotter. Take using hand graphics for what is worth. Getting good training is hard to find for certain disiplines, and usually expensive (a mistake in my opinion - how better to promote your software than teaching your users to use it to the best of their abilities - word of mouth and product will sell a program faster than an account exec.) That said, I often find the design process inhibited by the difficulty of learning computer graphics. My hand graphics are horrible, My computer graphics are fairly good, especially with many of the improvements programs such VW provide. Design approach is different using hand-drawn techniques vs computer. Put us side by side and our approach to a design problem is different, but often with the same results. He also is one of the finest with hand drawing. Having been in design for almost 30 years, I disagree with those who say design can only begin on paper, or the computer may hide drawing errors -sorry Paolo, the computer actually emphasises drawing error because of its precision. ![]()
