What is the difference between an auxiliary and a section view?

• A. An auxiliary view shows the true shape of inclined features; a section view shows a cut surface.
• B. An auxiliary view shows internal features; a section view shows external features.
• C. An auxiliary view is used for tolerances; a section view is used for finishes.
• D. An auxiliary view is color coded; a section view is black and white.

Answer: (A)

The main idea is how these two drawing tools reveal geometry differently. An auxiliary view is used to show the true size and shape of a surface that lies at an angle to the standard projection planes. By projecting onto a plane that's aligned with that inclined surface, you get an undistorted view of its contour, which is essential for understanding features like a slanted face or an inclined edge. A section view, on the other hand, comes from slicing the part with an imaginary cutting plane to expose what lies inside. The view shows the cross-section of the material along that plane, revealing internal features such as holes, slots, or cavities, typically with hatch marks to indicate the cut surface. So the statement matches because an auxiliary view preserves and clarifies the true geometry of inclined surfaces, while a section view reveals a cut surface to show interior details. The other choices mix up internal versus external visuals or bring in attributes (like tolerances, finishes, or color) that aren’t the defining difference between these two types of views.
