The CIMdata administered group presents their detailed requirements for the minimum CAD Part types and data items within each that are needed to develop, build, and certify an aircraft.
ANN ARBOR, Michigan, USA 2 February 2021—Representatives of the Aerospace & Defense PLM Action Group (AD PAG) have published a list of their detailed requirements for the minimum data items required for standard 3D Model-Based Definition (MBD) Type Design Certification. The requirements are the culmination of two years of effort by the team made up of domain experts from the eight-member companies and select Tier 1 suppliers.
The report documents the definition of use cases that encapsulate requirements for MBD within an aerospace original equipment manufacturer (OEM). The requirements list contains over 200 specific data items needed in an aircraft 3D MBD model. The list will be used to perform a gap analysis against various open data standards such as, but not limited to, ISO 10303-242 (STEP AP242), ISO14306 (JT), and ISO32000/14739 (PRC for 3D PDF), used to support data exchange and interoperability requirements for existing MBD design processes. The stated goal is to have each of the industry standards support the requirements equally and that any solution provider that provides a tool to data exchange their native formats into the specified standard formats does so equally.
The AD PAG members consider 3D MBD to be foundational to their Digital Thread strategies. According to Ken Versprille, Ph.D., Executive Consultant, CIMdata, who administered the group, “These detailed requirements represent a watershed milestone in CAD. We know of no other industry that has collectively documented their agreed-upon detailed MBD requirements. The effort provides both standards bodies and solution providers alike a road map for their future efforts in data exchange.”
Brandon Sapp, MIS, Boeing Enterprise Engineering and project leader of the A&D MBD Workgroup this past year, states, “As information captured within an MBD continues to grow and CAD authoring tools continue to improve their integration with the digital thread, a specific focus on how the information is represented is needed. The research in this paper is the first step in defining the semantic requirements of that information with the goal of retiring drawing-based concepts.”
Since its founding in 2014, the AD PAG, administered by CIMdata, has sponsored research and jointly staffed projects on a diverse set of prioritized industry and technology topics. These topics include Model-Based Definition, Multiple-View Bill of Materials, PLM Technology Obsolescence Management, Global Collaboration, and Model-Based Systems Engineering. As an outcome of these investments, the Group has released a series of direction statements and position papers that are freely available for downloading from its website at www.ad-pag.com. Making these materials available is consistent with the Group’s mission to engage proactively within the PLM ecosystem and advocate for common direction and positions within the aerospace and defense industry on PLM-related topics of importance to the members.
