Computers are a closed book to many of the older generations of model engineers, despite the fact that more than one-third of all British households now have a personal computer. By taking one step at a time, the computer can soon be tamed and turned into a versatile drawing tool with many advantages over traditional draughting methods. Derek Brown's demonstrations and lectures on the subject at various model engineering exhibitions over the past few years have proved very popular. In this book he seeks to strip away the mystique surrounding the subject by avoiding jargon and providing practical advice on how to choose the right system and to make progress with it.
