Which views show width? Does the width dimension appear in the rear, top, front, and bottom views in orthographic projection?

Introduction / Context:Each principal view in orthographic projection displays two of the three principal dimensions: width, height, and depth. Knowing where each dimension appears helps drafters place dimensions and choose the minimum set of views for clarity and completeness.

Given Data / Assumptions:

• Front and rear views are opposite faces; top and bottom are opposite faces.
• Width is the left–right horizontal dimension on the sheet.
• Standard view relationships apply independent of projection angle (first vs third).

Concept / Approach:The front (and rear) views show width and height. The top (and bottom) views show width and depth. Therefore, width appears in front, rear, top, and bottom. Side views (left/right) show height and depth and do not display width.

Step-by-Step Solution:

Verification / Alternative check:Sketch a simple block and label axes. Project to front, top, and right-side views; observe width on front and top. Repeat for bottom and rear; the same width is present by symmetry.

Why Other Options Are Wrong:

Common Pitfalls:Confusing “depth” with “width” in the top view; mislabeling axes when switching between views.

Final Answer:Correct
