This document specifies implementation guidelines for the exchange of validation properties with JT. It makes use of existing default properties as well as newly introduced properties to capture certain key aspects of the model that allow for validating the success of the data transfer after importing the JT file into a target application.

Validation properties have become a well-established mechanism to ensure data transfer quality in a variety of exchange formats. This document reuses existing concepts were applicable for consistency, so that applications handling multiple formats can apply these approaches in a universal manner.

The first revision of the implementation guidelines for JT Validation Properties covers geometric validation properties as well as validation properties for Product & Manufacturing Information (PMI). This scope might be extended in the future, depending on user requests.
