Which of the following is a common CAD tool used in product design?

SolidWorks is a premier Computer-Aided Design (CAD) tool widely used in product design and engineering. It is specifically designed for creating 3D models, simulations, and technical drawings that are essential in various industries such as mechanical engineering, product design, and manufacturing. Its robust features allow users to develop complex geometries, perform stress analysis, and generate assemblies, making it an invaluable resource for designers looking to streamline the product realization process.

In contrast, the other options listed are not CAD tools. Microsoft Word and Google Docs are word processing applications primarily used for document creation and text editing, lacking capabilities for 3D modeling and design. Adobe Photoshop, although a powerful tool for image editing and graphic design, does not focus on CAD functionalities required for product design. Thus, SolidWorks stands out as the appropriate choice for anyone involved in product design activities.
