Purpose / Scope

1

Dimensioning and Tolerancing

Defines how dimensions and tolerances should be applied, placed, and interpreted to control form, fit, and function.

2

Projection and Geometric Accuracy

Ensures correct orthographic projection, completeness of views, alignment, and functional control via datums and features.

3

Clarity, Layout and Conventions

Assesses layout organisation, legibility, view spacing, line conventions, and clarity of sectioning and simplified elements.

4

Annotations and Drawing Information

Covers notes, leader lines, repetition syntax, units, drawing metadata (e.g., title block, scale, drafter, date).

5

Manufacturability and Presentation
