Vistagy Inc.(Waltham, MA) will release new versions of its FiberSim and EnCapta design software at the National Design Engineering Show in Chicago March 18 to 21. EnCapta is computer-aided design (CAD) integrated software that enables engineers to capture, structure and communicate the specialized non-geometric design data for product definition. The software provides templates for defining the type and structure of information, such as design details, cost estimates, engineering change orders, materials specifications and assembly instructions that are often stored separately from the CAD model. The templates then enable engineers to associate this vital information with the relevant CAD geometry and features.
