A 3 view or shop drawing is the same thing as __________.

• A. A pictorial
• B. An axonometric projection
• C. An isometric drawing
• D. An orthographic projection

Answer: (D)

A 3-view or shop drawing uses orthographic projection. In this approach, front, top, and side views are drawn on perpendicular planes, showing the true shape and size of features in each direction without perspective distortion. This makes it ideal for manufacturing and inspection because every dimension is true in at least one view.

Pictorial drawings, like isometric or other axonometric projections, show a 3D appearance but not the separate views with true dimensions. An axonometric projection covers a family of 3D views; an isometric drawing is a specific type where all three axes are equally foreshortened. So the 3-view/shop drawing is the orthographic projection.
