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

• A. Revolve
• B. Sweep
• C. Loft
• D. Extrude

Answer: (A)

The command that allows you to create a feature by rotating a section string around an axis through a specified angle is Revolve. This method is fundamentally designed for generating symmetrical shapes or features from a 2D profile. When using the Revolve command, you select a section curve and then define an axis of rotation. The angle of rotation determines how far the section will be spun around the axis, effectively creating a three-dimensional object that resembles a lathed or turned part. It's commonly used in design for creating objects like cylinders, circular dishes, or features with a circular symmetry, which are prevalent in many mechanical and consumer product designs. Understanding this function is crucial for efficient model generation in CAD applications like NX, as it allows for rapid creation of complex geometries that follow simpler 2D sketches. Other options, such as Sweep, Loft, and Extrude, are used for different types of shape creation based on different methods of defining geometry, which do not involve rotation around an axis.
