What tool would you use to join two faces in Fusion 360?

The Combine Tool in Fusion 360 is specifically designed to merge or join different bodies or components within a design, making it the correct choice for joining two faces. When you use this tool, you can perform operations such as joining, cutting, or intersecting, which allows for the seamless integration of geometries. It enables you to select multiple bodies and define how you want them to interact – whether it’s to merge them into one single body or to change their configuration based on specific requirements.

The other tools mentioned serve different purposes and are not intended for joining faces. The Sketch Tool, for instance, is primarily used for creating 2D outlines and profiles, which can be extruded or revolved into 3D shapes, but it doesn’t perform any joining actions. The Fillet Tool is used to create rounded edges or corners on existing geometry, enhancing aesthetics and functionality, rather than merging surfaces. The Pattern Tool is utilized for replicating features or geometries in a systematic way, whether in linear, circular, or rectangular arrangements, but it does not combine or join existing faces. Thus, the Combine Tool stands out as the most appropriate tool for the task of joining two faces in Fusion 360.
