Studies indicate that as many as half the parts designed in CAD cannot be manufactured cost effectively or work the first time. The training-free software, aimed at designers and engineers, performs quick and easy studies of the effect of tolerances on assembly performance and manufacturing quality at any stage of the design process. An important feature is the ability to develop instantaneous Sigma-quality values for any given manufacturing and performance criteria at any stage of the design process. This feature was designed to help companies wanting to adopt DFSS (Design for Six-Sigma) product quality goals. Price: $395.
