Solidworks is a 3D mechanical CAD (Computer Aided Design) solid modeling software developed by Dassault Systèmes SolidWorks Corp to create 3D digital prototypes. It is used for 3D mechanical design, design communication, tooling creation and product simulation. This software enables users to produce accurate 3D models that can help you design, visualize and simulate products before they are built. Digital Prototyping with Solidworks helps companies design better products, reduce development costs, and get to market faster. It is user-friendly and easy to learn. Furthermore, the software comes with installed tutorials which can help you a lot.
On the other side, one thing I personally dislike is the lack of lighting options. Also, when it is used heavily, it crashes or freezes.
With that said, I believe that by making a couple of modifications to the internal operating system, the lighting options and the usage ability; Solidworks can become the most strong 3D Modeling software available in the market.
