SOLIDWORKS is a very productive 3D CAD software tool, with its integrated analytical tools and design automation to help stimulate physical behaviour such as kinematics, dynamics, stress, deflection, vibration, temperatures or fluid flow to suit all types of design.
SolidWorks is a *very* powerful design and analysis program. If you need some rudimentary 3D modeling, SolidWorks, like most professional design software, is much more tool than you need.
