Dimensioning standards and responsibility The American Society of Mechanical Engineers (ASME) publishes widely used industry standards that govern the placement and presentation of dimensions on technical drawings.

Introduction / Context:
Consistent dimensioning is essential for manufacturing, inspection, and lifecycle documentation. ASME standards (for example, dimensioning and tolerancing and related practices) provide a common language so designers, machinists, quality engineers, and suppliers interpret drawings the same way, minimizing errors and rework.

Given Data / Assumptions:

• Mechanical drawings must communicate unambiguous size, location, and tolerance information.
• Organizations often adopt a national or international standard as baseline.
• Company supplements may add details but should not conflict with base standards.

Concept / Approach:
ASME documents define rules for where to place dimensions, how to avoid duplication, how to select datums, how to express limits and fits, and how to apply geometric tolerancing. Using these norms ensures drawings are readable across teams and vendors. ISO provides parallel international standards; many firms choose one family and reference it in the title block.

Step-by-Step Solution:

Verification / Alternative check:
Conduct peer reviews or use checklist-based CAD audits to ensure standard conformance before release to manufacturing.

Why Other Options Are Wrong:
Claiming “Only local company rules apply” risks inconsistency. “Only ISO publishes such standards” ignores ASME’s role. Restricting usage to architects is incorrect; mechanical and many other fields rely on these standards.

Common Pitfalls:
Mixing ASME and ISO conventions on the same drawing set, omitting the standards reference, or using nonstandard symbols.

Final Answer:
Correct
