Purpose of assembly views: In an assembly drawing, should selected views be chosen to clearly show how parts fit together and to suggest or communicate the function of the overall unit?

Introduction / Context:
Assembly drawings communicate how components come together to create a functioning product. The choice of views directly affects whether readers can understand interfaces, motion, and critical alignments. This question reinforces the intent behind selecting assembly views.

Given Data / Assumptions:

• The drawing audience includes machinists, assemblers, and inspectors.
• Bill of materials and callouts are provided.
• Clarity of fit and function reduces assembly time and errors.

Concept / Approach:
Views should maximize comprehension: orthographic views to show datum alignment and clearances, sections to reveal interior fits, and occasionally exploded or auxiliary views to visualize sequence and relationships. The drawing should make it evident how parts locate and what the assembly does, supplemented by notes and critical dimensions as needed.

Step-by-Step Solution:

Verification / Alternative check:
Have a technician unfamiliar with the product interpret the drawing. If they can identify how parts fit and what the unit does without additional explanation, the views successfully communicate fit and function.

Why Other Options Are Wrong:

• Hiding interfaces (option B) defeats the purpose of assemblies.
• Decorative perspectives alone (option C) lack precise dimensional control.
• Forbidding function inference (option D) ignores practical needs of assembly and QA.
• Showing parts separately only (option E) prevents understanding of real interfaces.

Common Pitfalls:
Failing to use a section where it would clarify a hidden fit; overreliance on a single view; neglecting to include notes about motion direction or safety-critical alignments.

Final Answer:
Correct: views should reveal fit and suggest function
