Annotation of standard text ČSN EN 9300-120 (310450):
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). This document does not apply to: - machine-interpretable PMI "Representation"; - how to preserve additional information: - property rights; - form features; - machining features; - CAD Assemblies
