2.30 Reviewing Detailed Drawings. Reference ASME Y14.3M. Check the following:
- Detailed drawings must completely depict the entire part or assembly shown.
- Ensure that there are sufficient views to adequately define the item.
- If directly tolerancing (+/-) is used, ensure that the origin for every dimension is clearly defined and taken from a (physical) feature. Generally, direct tolerancing methods (+/-) should only be used to define the size and form for features of size. Geometric Dimensioning and Tolerancing (GD&T) should be used to define all other features and feature relationships to avoid ambiguous specifications. Reference ASME Y14.5M-1994.
- Dimensions and tolerances should not be directed to features depicted by hidden lines in a view. Dimensions and tolerances should be applied to true profile views where possible. Reference ASME Y14.5M-1994.
- Ensure that datum reference frames are properly defined. Reference ASME Y14.5M-1994.
- Ensure that mono-detail drawings depict only one item.
