Which command creates circular cuts or holes in parts?

The Revolution command is used to create circular cuts or holes in parts by revolving a profile around an axis. This operation is particularly suited for generating features such as cylindrical holes or intricate shapes which require a rotational motion. When a 2D sketch, which could represent the desired cut profile, is revolved around an axis, it effectively creates a 3D feature that can result in either a solid or cut body depending on the settings applied.

In contrast, the other commands have different functions: the Extrude command typically extends a 2D shape linearly in one direction, perfect for creating rectangular cuts or adding material but not for circular holes specifically. The Fillet command adds a rounded edge between two surfaces, which does not create holes but instead modifies existing geometry. The Chamfer command creates a flat edge between two surfaces, useful for creating bevels rather than circular features. Understanding the specific purpose of these commands is essential for effectively using Autodesk Inventor to model parts accurately.
