In scope

This document is applicable to:

- the Presentation of 3D geometrical dimension and tolerance, and 3D annotation attributes;

- their possible semantic links with 3D Geometric shape;

- User Defined Attributes: that are assigned to 3D geometric entities or at the part level.

For the purpose of this document, the semantic definition is at the level that supports associative "Crosshighlighting", to illustrate the portion of the geometry to which a PMI element applies.

In this version, the technology used to preserve this 3D information is based on polyline and tessellated presentation. Polyline presentation is a conversion to lines and curves of all 3D annotations by the STEP interfaces of the CAD system, including validation properties. Tessellated presentation is a conversion to tessellated curves and tessellated faces. The main use cases are the Certification and Product Liability of static information, however, re-use is also possible after the deletion of previous PMI and creation of new PMI (refer to clause 3 for definition).

Out of scope

This document does not apply to:

- machine-interpretable PMI "Representation";

- how to preserve additional information:

- property rights;

- form features;

- machining features;

- CAD Assemblies.
