New ANSI Standard Emerging from DMSC Characteristics Working Group

The DMSC Characteristics Working Group has created multiple iterations of a Model-Based standard to describe nomenclature, definitions, data structure, criticality, symbols, and practices, including Model-Based Definition (MBD) with Persistent Identification. The Characteristics Working Group’s intent is to complete a draft standard for submission to ANSI, a document that can be used as a new reference for the interpretation of features and design intent throughout the manufacturing supply chain.

The Characteristics Working Group, initiated in July 2020, is co-chaired by Curtis Brown (Honeywell) and Mark Neilson (TechAzul). The participants, mostly from DMSC member companies, are engaged as a joint effort by multiple corporate and academic entities representing various manufacturing industries.

The Characteristics Working Group meets (virtually) twice a month and is currently up to “Revision C” of a 47-page draft standards document with representatives from up to 20 global companies participating at any given meeting.  Meeting details on this and other DMSC Working Groups can be found on the DMSC Events Calendar.

New participants (including non-DMSC members) are welcome to observe or participate.

Model-based definition is an approach to creating 3D models so that they effectively contain all the data needed to define a product. With MBD, the model becomes the source authority that drives all engineering activities. The model may further be used downstream by suppliers and across organizations within an enterprise.
