Fortunately, Capvidia is a leader in Boeing DPD and is here to answer some of your important questions. Let's begin.
What is Boeing Digital Product Definition
Boeing DPD is a quality assurance standard for
The Boeing D6-51991 (current version: REV N) is the official document that outlines the following:
Digital Product Definition Quality Assurance Procedures and Documented Processes
Configuration Management and Media Security
Internal Quality Audits
Procurement Control
Control of Measurement Equipment
Inspection Media
Data Exchange Methods
Special Tooling
Training and Process Performance Why is Boeing DPD Important Uniformity and traceability.
Different CAD software, different file formats, different revisions, different departments, different personnel, and different interpretations eventually lead to discrepancies.
Ensuring that the electronic data or digital models follow a set of protocols verifying consistent data saves time and money, because fixing errors earlier in the design phase saves up to 2X in cost compared to the build phase or 3-10X compared to the testing phase.
In short, data downstream from design to manufacturing to quality must be validated.
This is part of a larger theme of digital transformation as more companies require a single source of truth generated from the CAD model called model-based definition (MBD).

Here's a highlight of the main points:
3.1.4. In the event supplier is unable to obtain objective evidence or certification of the PAS from the software manufacturer, supplier is responsible for verifying PAS prior to product acceptance use. Examples of PAS functionality verification include using calibrated standards, known physical artifacts or embedded software to test feature construction and output accuracy. Examples also should include GD&T functions, temperature compensation, CAD translations and software that controls hardware.
Inspection Media: 7.5. Model Based Definition (MBD) - Suppliers who receive Engineering and/or Tooling MBD datasets must extract information from the dataset sufficient for manufacturing and inspection activity for the product. Additionally, utilizing MBD requires a capability assessment by a Boeing Supplier Quality DPD.
7.5.1. Supplier's QA must verify that all design implicit and explicit requirements (e.g., all features defined by GD&T, annotations, specifications, notes and other specified requirements in the authority MBD dataset and associated parts list including dimensional and other planned for inspection/validation.
7.6. First Article Inspection - All explicit and implicit design characteristics within the engineering shall be positively identified within the FAI plan. This shall include all engineering characteristics requiring traceability: a) All features annotated within the 3D model (explicit) b) Features of the 3D model not annotated (implicit) c) All characteristics applicable on the 2D drawings/reduced content drawings d) All applicable notes and material lists e) All feature tolerances per the standard / general notes.
Data Exchange Methods: 8.2. Translations - When suppliers with native
Main Takeaways: 1. Your derivative CAD model must be validated so that it matches the authority model fromBoeing .
The software you use to validate the derivative CAD model must be a current version from an approved vendor.
