What is defined as a collection of parts in SolidWorks?

An assembly in SolidWorks is defined as a collection of parts that are combined to create a larger model. In an assembly, individual parts can be joined together using various mating relationships, which helps to define how the parts interact with one another. This allows engineers and designers to visualize and analyze the functionality of the entire system rather than just individual components.

Assemblies can include parts, sub-assemblies, and even purchased parts, which are crucial in the design process to ensure all components fit together correctly. This concept is essential in product design and simulation, as it allows for a comprehensive understanding of the overall structure and function of the designed product.

Other options refer to different elements within SolidWorks: a sketch is a 2D drawing used to create features, a drawing represents the technical documentation of a part or assembly, and a feature is a specific operation or shape created on a part, such as a hole or boss. None of these terms represent the overarching organization and functionality of parts that an assembly does.
