What is the primary benefit of using the 'Mirror' command in Autodesk Inventor?

The 'Mirror' command in Autodesk Inventor is primarily beneficial for creating symmetrical designs efficiently. This feature allows users to generate a reflective copy of a sketch, part, or feature along a specified axis. By utilizing the 'Mirror' command, designers can save time and effort as it eliminates the need to manually recreate identical geometry on both sides of a symmetrical design. This not only streamlines the design process but also helps maintain design integrity, as any adjustments made to the original geometry automatically reflect on the mirrored counterpart.

Reducing file size is not directly associated with the 'Mirror' command; while it may incidentally help with managing design complexity, the primary purpose focuses on replicating geometry. Similarly, applying textures over surfaces pertains to the visual aspect of models rather than geometry duplication. Lastly, duplicating assemblies involves different techniques suited for handling multiple components, rather than mirroring features within a single part or sketch.
