Apollo Computer Inc is looking for business from mechanical engineers for its Series 3000 and 4000 workstations with the announcement of two new mechanical computer-aided engineering packages. Cognition Inc, Billerica, Massachusetts has developed an expert system, CMG, for mechanical engineers which provides costing and manufacturing aid feedback during the early phases of the design process. CMG is intended to help engineers identify major cost drivers in a design, suggesting aspects that can be changed to reduce cost. It is also designed to help engineers identify manufacturing problems which should then mean that the design is corrected before money is wasted producing faulty products. ProEngineer, from Parametric Technology Corp of Waltham, Massachusetts, is a parametric, feature-based solid modelling program claimed to be the first such to support interactive design modifications to models of assemblies and parts; it captures functional relationships among assemblies, parts, features and parameters and incorporates unique dimension-driven solid modelling technology.
