We engineers speak the language of numbers. There is no such thing as general solution for example there are thousands of scales on the market. With one you can weigh a truck, with the other one a fruit fly -- Could you design a cheap one which can do both ?
Let's suppose you want to design a 1 inch iron cube. If 20 mils tolerance and .99% pure iron is acceptable, it may be a 15 minutes of design work and a dime a piece.
If the tolerance is .1 mil and the purity is 99.9999 % it may be a few hundred bucks each.
Adding a few "0"-s and "9"-s after the two decimal points may cost more than a new Manhattan project.
A few more and it will be and will remain forever mpossible for any price.
So if you want to save time and money : SPECIFY IT !!!
