What command allows you to create a feature by rotating a section string around an axis through a specified angle?

The command that allows you to create a feature by rotating a section string around an axis through a specified angle is the Revolve command. This functionality is particularly important in CAD modeling as it helps in generating 3D shapes from 2D profiles. When you use the Revolve command, you define a profile (the section string) and an axis of rotation, along with the angle through which the profile should be rotated. This results in a symmetrical 3D object that is often seen in parts like cylindrical features, knobs, and other round components.

The other commands listed serve different purposes. The Spin command typically involves changing the view orientation or rotating objects in the workspace but does not create features. The Rotate command usually refers to rotating objects or views within the workspace rather than generating a new feature from a profile. The Sweep command, while also valuable in feature creation, involves moving a profile along a specified path rather than rotating it around an axis.
