Abstract

1 Scope

1.1 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 “Cross-highlighting”, 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).
