What feature allows the creation of a 3D representation of an object such as a baseball bat?

The feature that allows the creation of a 3D representation of an object like a baseball bat is the "Revolve" option. In computer-aided design (CAD), revolve is a modeling technique used to create a 3D shape by rotating a 2D profile around a specified axis.

For a baseball bat, the profile could represent the cross-section of the bat, showing its shape at one end. By revolving this profile around an axis (which would typically be the long central line of the bat), you generate a smooth and symmetrical 3D model that resembles the actual form of the bat.

Other methods such as extruding, lofting, and sweeping involve different design approaches. Extrusion extends a 2D shape into the third dimension, which may not effectively capture the curved and tapered profile of a bat. Lofting creates a shape by connecting multiple profiles, useful for more complex geometries. Sweeping involves moving a profile along a path, which is not applicable to a simple cylindrical shape like that of a baseball bat.
