Key distinction – isometric vs. perspective: In isometric drawings, vertical and “horizontal” axes remain parallel (no convergence), whereas in perspective drawings, those directions visually converge toward vanishing point(s). Decide whether this comparison statement is accurate.

Difficulty: Easy

Correct Answer: Correct

Explanation:


Introduction / Context:
Understanding projection types is essential for selecting the right view method. Isometric is a parallel projection; perspective is a central projection with convergence. This question asks you to confirm the fundamental difference.


Given Data / Assumptions:

  • Isometric: three axes at 120 degrees; lines parallel in the object remain parallel in the drawing.
  • Perspective: receding parallels meet at vanishing points; realism increases with appropriate camera setup.
  • Verticals may also converge in three-point perspective.


Concept / Approach:
Parallel projection eliminates convergence effects; it preserves parallelism to aid measurement-like interpretation. Perspective mimics human vision: parallel edges not parallel to the picture plane appear to meet at finite vanishing points on or off the horizon.


Step-by-Step Solution:
Identify projection type: parallel (isometric) vs. central (perspective).Check for vanishing points: none in isometric; one, two, or three in perspective.Confirm that the statement captures this essential difference.


Verification / Alternative check:
Visualize a cube: in isometric, top edges remain parallel; in perspective, edges recede to vanishing points, altering apparent size with distance.


Why Other Options Are Wrong:
Restrictions to aerial views, infinite focal length, or specific numbers of vanishing points distract from the general principle.


Common Pitfalls:
Assuming orthographic views equal isometric; forgetting that three-point perspective converges verticals too.


Final Answer:
Correct
