Which statement about an isometric drawing is correct?

• A. All three axes are not equal in scale
• B. All three axes are at equal scale, creating a pictorial view
• C. It shows the plan from a bird’s eye view
• D. It represents only electrical wiring

Answer: (B)

Isometric drawings present three dimensions by foreshortening each axis equally, so no axis looks longer or shorter than the others. The axes are arranged so you can see the front, side, and top in one view, producing a pictorial representation that preserves true scale along each direction. That’s why the statement describing equal scaling across all three axes creates a pictorial view is the best answer. It’s not just a bird’s-eye top view, and it isn’t limited to electrical wiring—isometric drawings are used for a wide range of objects to show how parts fit together from multiple angles.
