What does the "Combine" tool do?

The "Combine" tool in Fusion 360 is specifically designed to manipulate solid bodies in various ways, including merging them, cutting one from another, or creating an intersection between them. This capability is essential for complex modeling tasks where you need to create a new geometry from existing parts. By using the Combine tool, you can efficiently create more intricate shapes and components by manipulating existing solid bodies.

For instance, if you have two overlapping solid bodies and you want to create a single unified part, the merge option of the Combine tool will do just that. Conversely, if you want to create a hole in one body using the shape of another, the cut option allows you to subtract the volume of the second body from the first. The intersection option would give you a solid that represents only the volume where both bodies overlap.

The other options do not accurately describe the primary function of the Combine tool. Dimensioning is related to adding measurements and annotations to the design, creating 2D sketches involves drawing shapes that can be extruded into 3D bodies, and importing external models pertains to bringing in designs made in other software. Each of these features serves different purposes within Fusion 360, making it important to understand that the Combine tool’s primary role is focused on
