PDM-UG: Additional Part Properties

From WikiSTEP

This page belongs to the PDM Usage Guide.

Several implementations and pilot projects have identified the requirement to exchange additional properties beyond the pre-defined values given in Pre-Defined Properties. One example of such a user defined property is the notes/remarks related to a product. A remark is some text that while associated with a part does not identify or describe it. These general remarks associated with part meta data are mapped to descriptive_representation_items related to the product_definition via a property_definition. This instantiation structure captures the actual text of a note/remark as a remarks property in the STEP file. The property_definition.name = 'remarks property' may be used to identify such a property. An alternative external representation of related notes/remarks as a 'document' (see Document as Product) or a 'file' (see External File Identification) makes reference to, but does not capture the actual text.
