Design employees from three companies participated in a study carried out to examine their experiences of computer-aided-design work. Most of the CAD users appreciated the ease in altering drawings and the ease in testing alternative solutions offered by CAD systems. Dependence on the CAD system was disadvantage reported by many CAD users and one-quarter of them experienced a sense of inadequacy in relation to the system as a consequence of difficult commands and confusing information obtained from the system.
