Final answer:
A half-section view is a type of engineering drawing that shows half of an object to reveal its internal features.
Step-by-step explanation:
A half-section view is a type of engineering drawing that shows one-half of an object, typically at the cutting plane. It is used to reveal the internal features of the object that are hidden in the regular view. In a half-section view, exactly half of the view is removed to expose the internal details of the object.
