Which feature in SolidWorks would you use to combine multiple parts into a single component?

The feature used to combine multiple parts into a single component in SolidWorks is the Assembly function. In an assembly, various individual parts can be brought together and mated, demonstrating how they fit and function together as one cohesive unit. This is essential in mechanical design as it allows for the visualization and analysis of how different components interact within a single system.

The assembly process is fundamental for products that consist of multiple interconnected parts, and it allows for greater organization and management of complex designs. While features like extrude, fillet, and revolve are used to create or modify individual parts, they do not provide the capability to combine multiple parts in the same manner that the assembly feature does.
