Difficulty: Easy
Correct Answer: All of the above
Explanation:
Introduction / Context:
Manual drafting remains relevant for fundamentals training and quick sketching. Recognizing core tools helps students select the correct equipment and understand historical conventions reflected in CAD standards.
Given Data / Assumptions:
Concept / Approach:
Each tool fills a specific geometric role. Together they enable orthographic views, isometric axes, and standard geometric constructions before dimensioning and notation are added.
Step-by-Step Solution:
Verification / Alternative check:
Introductory drafting texts depict these items as standard; course supply lists typically include all three.
Why Other Options Are Wrong:
Each of A, B, and C is indeed a standard tool; therefore the combined choice “All of the above” is correct.
Common Pitfalls:
Relying solely on freehand lines reduces accuracy; always reference the parallel bar and triangles for precision.
Final Answer:
All of the above
