Difficulty: Easy
Correct Answer: Incorrect
Explanation:
Introduction / Context:Parametric CAD captures design intent with dimensions and constraints that drive geometry updates. While AutoCAD offers constraints and parameters for 2D sketches, it is not a fully history-based parametric solid modeler like Inventor, SolidWorks, or Creo. This question distinguishes drafting-centric workflows from full parametric modeling.
Given Data / Assumptions:
Concept / Approach:Compare feature scope: fully parametric systems drive solids via sketches, features, dimensions, and relations with a history tree. AutoCAD has limited parametric features primarily for 2D and lacks a full 3D parametric feature history comparable to dedicated parametric platforms.
Step-by-Step Solution:
Step 1: Identify hallmark of parametrics: constraints drive updates automatically.Step 2: Evaluate AutoCAD's capability: constraints exist but not a full feature history for solids.Step 3: Conclude that AutoCAD is not “typical” of parametric modelers.Verification / Alternative check:Open a complex solid in AutoCAD vs Inventor. Observe absence of a feature tree and limited edit propagation in AutoCAD compared with true parametric systems.
Why Other Options Are Wrong:Claims that AutoCAD is fully history-based or that parametrics depend on DYN/paper space are incorrect. The “Correct” option conflicts with mainstream categorization.
Common Pitfalls:Equating presence of constraints with full parametric modeling; assuming identical behavior across distinct CAD families.
Final Answer:Incorrect
