The impact of CAD (computer-aided design) on employment and skill is examined. First, the relationship between the adoption of mechanical CAD systems and employment of drafters in the aerospace and automobile industries is assessed. Contrary to many employment projections, drafting employment in these industries increased with increases in the adoption of CAD systems. Second, the effects of design automation and skill transformation capacities of electronic CAD systems on printed circuit board designers are evaluated. Third, the limits to automation of design are explored, suggesting that there are trade-offs between automation of the design process and innovation in product design. The logical limits of software, flaws in programming, and the dynamic nature of product markets are evaluated as factors limiting automation.>
