Dassault Systemes SolidWorks Corp., Concord, MA, has introduced SolidWorks® 2012 3D design software that features improvements in assembly and drawing capabilities, built-in simulation, design costing, routing, image and animation creation, and product data management. The new version lets users automate the design functions they use most often, and supports collaboration and team connectivity. New drawing tools enable changed dimensions to be automatically highlighted, and previous values are shown to help with revisions. Large design review allows instant opening and review of massive assemblies or any individual component with walkthroughs, sectioning, and measuring. Feature freeze eliminates unwanted feature rebuilds by locking all features above the “freeze” bar, speeding up the design of complex models. An equation editor allows users to create equations faster and understand order more easily. A design costing tool automates manufacturing cost calculations for sheet metal and machined parts. SolidWorks Simulation includes enhanced motion optimization that automatically uses motion study results to create sensors and refine complex machine aspects such as motor size, bearing loads, and range of travel.
