    Abstract

    Sophisticated CAD/CAM applications in Science and Engineering involve heavy number-crunching necessitating high-performance CPU, offering a rating of one Mip or more on the whetstone benchmark. To match such a CPU, a workstation must have a dedicated and fast graphics processor offering high rates of vector generation, area-fill and bit-block transfers. Such performances must13; be aided by a multi-tasking Virtual Operating System and a comprehensive graphics tools-kit, which enable geometric-modelling and post-processing to be done in a fast user-friendly environment using a vast. repertoire of hardware and software interactive tools. Criteria for evaluating a CAD workstation are examined in the paper with particular reference to some stand-alone 32 bit workstations offered by some leading manufacturers.
