Which command would you use to merge multiple bodies in a design?

The command used to merge multiple bodies in a design is the Combine command. This command is fundamental in Fusion 360 for managing different components within a single design workspace. It allows users to combine multiple solid bodies into one, which is crucial for simplifying complex assemblies and facilitating further design operations.

When using the Combine command, you can choose different operations such as Join, Cut, or Intersect, but the act of merging—specifically combining multiple bodies together into one is effectively realized through this command. It streamlines the workflow, especially in scenarios where multiple parts need to be treated as a single entity for functions like creating assemblies, running simulations, or preparing for manufacturing.

While other options may sound relevant in certain contexts, they do not specifically address merging multiple bodies. The Join operation can be part of the Combine command, but it is not standalone for the purpose of merging multiple bodies as a singular action. Therefore, the Combine command is the most accurate choice for the task of merging multiple bodies in Fusion 360.
