SolidWorks is a powerful computer-aided design (CAD) software used for creating 3D models, simulations, and technical drawings. Developed by Dassault Systèmes, it is primarily used by engineers, designers, and manufacturers to design and visualize products in industries like automotive, aerospace, electronics, machinery, and more.

Key features of SolidWorks include:

1. 3D Modeling: Allows users to create complex 3D parts and assemblies using parametric design techniques.
2. 2D Drafting: Users can create detailed 2D drawings, annotations, and dimensions, making it easier to communicate design specifications.
3. Simulation: SolidWorks includes simulation tools to test the strength, durability, and performance of designs through stress analysis, fluid dynamics, and motion studies.
4. Rendering: It offers photorealistic rendering tools for creating realistic visuals of models.
5. Manufacturing Support: The software supports CAM (Computer-Aided Manufacturing) processes, helping translate designs into manufacturable products.
6. Collaboration: It includes tools for collaborating with team members, sharing designs, and maintaining version control.

SolidWorks is popular for its user-friendly interface and broad functionality, supporting both beginners and advanced users in the field of design and engineering.
