Annotation of standard text ČSN EN 9300-125 (310450):

This document specifies the requirements for the long term digital preservation of the presentation of Product and Manufacturing Information (PMI) with their possible links to the 3D explicit shape and geometry of CAD assembly structure. The goal is to preserve this 3D information, without loss, with respect to the geometry produced by the original CAD system, following the principles laid down in EN 9300-003 ´Fundamentals and Concepts´.
This will allow the retrieval of the assembly structure including the placement information.
This document extends EN 9300-115 "Explicit CAD Assembly Structure" by including assembly level PMI.
PMI for the assembly structure can be recorded in the same file as the geometry, can be in a nested assembly structure or the PMI will be contained in its own separate file (Side-Car).
The PMI elements shall be presented on the graphic level only (i.e. polyline, tessellated)
