View alignment rule: Do the rear, left-side, front, and right-side orthographic views align horizontally in standard multiview layouts?

Introduction / Context:
Consistent alignment is the backbone of reading multiview drawings. Horizontal and vertical alignments ensure that a feature’s position is traceable across views without guesswork.

Given Data / Assumptions:

• Standard orthographic layout conventions are followed.
• Front view is the anchor; side views are placed laterally; top/bottom views vertically.
• Rear view is a principal view placed opposite the front, typically aligned horizontally.

Concept / Approach:
In both first- and third-angle, the lateral views (left, right, and often rear) line up horizontally with the front view, sharing the same height reference. Vertical alignment is used for top and bottom views relative to the front. While the physical placement (left/right) differs between first- and third-angle, alignment along the horizontal axis remains consistent for lateral views.

Step-by-Step Solution:

Verification / Alternative check:
Project construction lines from the front view horizontally into side/rear views. Heights of corresponding features will coincide, confirming horizontal alignment in standard practice.

Why Other Options Are Wrong:

• Limiting alignment to the right-side ignores the general rule.
• Claiming vertical-only alignment misstates the layout; lateral views use horizontal alignment.
• First- vs. third-angle changes placement, not the principle of alignment.
• Symmetry is irrelevant; alignment is a projection rule, not a shape property.

Common Pitfalls:
Confusing view placement differences between first- and third-angle with loss of alignment; failing to carry projection lines, leading to mismatched heights across views.

Final Answer:
Correct: these lateral views align horizontally with the front view
