What is a common purpose of using assemblies in SolidWorks?

Using assemblies in SolidWorks serves a critical role in visualizing how components fit and function together. When multiple parts are combined into an assembly, users can interactively check the alignment, fit, and motion between different components. This capability is essential for engineers and designers as it allows them to see potential interferences, assess movement, and make necessary adjustments before manufacturing.

While drawing 2D representations, developing software documentation, or creating architectural layouts are important tasks in the design process, they do not utilize the strengths of assemblies. Assemblies focus on the interaction and relationship of parts, making them a key feature in the design and engineering fields for ensuring that mechanical systems operate as intended.
