Which of the figures shown in the illustration depicts an orthographic projection? Illustration GS-0142
• Difference between orthographic projection and perspective projection • How multiview drawings (front, top, side) of the same object are arranged on paper • Role of projection lines and angles (30°, 45°, vanishing lines) in technical drawings
• Look at which figure shows separate flat views of an object, rather than a single 3D-looking view. • Identify which figures use angles like 30° or 45° to show depth, and which figure does not rely on angled edges for depth. • Decide which figure could be used as a shipfitter’s or machinist’s working drawing where each face is shown full size without perspective.
• Verify which option shows no convergence of lines toward a point (no vanishing point). • Check which option represents each face in true shape and size, as if you are looking straight at each surface. • Confirm that the correct figure could be labeled as front view, top view, and side view of the same box.
