How can you create an assembly in Fusion 360?

Creating an assembly in Fusion 360 is best achieved by starting a new document and inserting components into the design. This method allows you to effectively manage different parts and their interactions as they come together in a complete assembly. When you open a new document, you have the freedom to sequentially import or design each component, establishing their relationships and constraints within the assembly environment. This process ensures that you can fully control the positioning, assembly workflow, and assembly joints right from the beginning.

Opening an existing assembly file serves as a starting point for review or modifications rather than the process of creating a new assembly. Merging multiple sketches is more about combining design ideas and does not align with the concept of constructing an assembly where physical parts are involved. Exporting components may be part of a collaborative workflow or a way to manage files, but it does not directly contribute to the creation of a new assembly within the Fusion 360 interface.
