Which command is used to create a fillet in Autodesk Inventor?

The Fillet command is specifically designed for creating rounded transitions between two intersecting edges or surfaces in a 3D model. This command allows users to specify the radius of the fillet, enabling seamless connections that improve both the aesthetics and functionality of the design. Fillets are frequently used to eliminate sharp corners that could be prone to stress concentrations or damage, enhancing the overall durability of the component.

In contrast, the Round command might seem relevant because it also pertains to rounding edges, but it does not specifically apply to the creation of fillets like the Fillet command does. The Groove command serves a different purpose, typically used for creating cuts or channels, and would not create the smooth transition characteristic of a fillet. Similarly, the Chamfer command is employed to create angled transitions rather than rounded ones, making it unsuitable for achieving the specified fillet geometry. Thus, the Fillet command is the appropriate choice for this task within Autodesk Inventor.
