What feature would you use to create a curved edge on a part in Autodesk Inventor?

To create a curved edge on a part in Autodesk Inventor, the most suitable feature is the fillet feature. This feature allows you to round off the edges of a part, giving it a smooth transition between two surfaces or edges. The fillet feature can be applied to various types of edges and allows for different radii to achieve the desired curvature.

In the context of the other features, the chamfer feature is used to create a beveled edge on a part rather than a curved one, resulting in a straight-line transition rather than a smooth curve. The bend feature is specifically designed for sheet metal applications to create a fold or bend in a flat part, rather than modifying the edge curvature. The emboss feature is used to add raised or recessed features onto the surface of a part, which does not directly create a curved edge. Each of these features serves distinct purposes, but for rounding edges, the fillet feature is the appropriate choice.
