CAD Practice — Auxiliary views of 3D parts can be created efficiently in AutoCAD and similar CAD tools by reorienting the UCS or defining view planes aligned to inclined faces.

Answer

Correct Answer: Correct

Explanation

Introduction / Context:CAD platforms streamline auxiliary-view creation using features like UCS reorientation, named views, and construction-line tools. This accelerates producing true-shape views for inspection and dimensioning.

Given Data / Assumptions:

  • Part geometry includes inclined faces.
  • CAD supports UCS alignment and orthographic viewing.
  • Projection remains parallel (orthographic), not perspective.

Concept / Approach:By aligning the viewing plane with an inclined surface, CAD shows that surface in true size. Geometry and dimensions placed in this orientation avoid foreshortening and confusion.

Step-by-Step Solution:1) Identify target face; set UCS parallel to it.2) Use offset/construction lines to project references.3) Create the auxiliary view and annotate.4) Save a named view for repeatable workflows.

Verification / Alternative check:Measured lengths on the auxiliary view match true lengths of edges lying in the plane; if not, the UCS is misaligned.

Why Other Options Are Wrong:Manual drafting is not required; perspective is not used for orthographic auxiliaries; applicability is not limited to sheet metal.

Common Pitfalls:Leaving the UCS in an unintended state; dimensioning from the wrong view; omitting clear labels for auxiliary views.
