CAD output modes: Most solid modeling CAD programs can generate pictorial representations of 3D objects using isometric views, perspective views, or both. Evaluate this assertion.

Difficulty: Easy

Correct Answer: Correct

Explanation:


Introduction / Context:
Modern CAD environments offer multiple camera and projection modes: orthographic (including isometric orientation) and perspective. This question checks familiarity with typical visualization capabilities of solid modeling software.


Given Data / Assumptions:

  • Most 3D CAD provides orthographic views (front, top, right) and isometric orientations for engineering clarity.
  • Perspective projection is available for realistic visualization and presentations.
  • Display modes include wireframe, hidden-line, shaded, and rendered.


Concept / Approach:
Isometric and perspective views serve different needs. Isometric maintains true scale along the isometric axes (with consistent foreshortening) for measurement-like clarity. Perspective mimics human vision with vanishing points for realism. CAD supports toggling between these for both design evaluation and documentation.


Step-by-Step Solution:
Open a 3D model and switch visual styles.Choose an isometric orientation (e.g., SW Isometric) for orthographic-based views.Activate a perspective camera to see convergence and depth cues.Confirm that both modes are standard across modern tools.


Verification / Alternative check:
Vendor documentation commonly lists both “parallel” (orthographic) and “perspective” projections as built-in options.


Why Other Options Are Wrong:
Restricting to parametric, hidden-line, or disabling rendering is unnecessary; these features exist broadly across platforms.


Common Pitfalls:
Assuming perspective is “only for rendering” and not available in modeling viewports; confusing orthographic isometric with perspective.


Final Answer:
Correct
