Abstract :
A basic problem in buying a CAD system arises from the fact that, if you do not know where you are going, any road will take you there. The solution is to plan where you want to go, and the rest more-or-less follows. The author shows how there are several ways in which you can acquire the expertise so that you can define your destination (i.e. your total CAD requirement) and hence plan your route (the justification and selection of the system)
