2 Model-Based Definition What is it? Why Model-Based Definition? What tools are required to define the model? What are the down-stream benefits?

3 Modeling Paradigms Master 2D Drawing Drawingbased Model- Centric 3D CAD Model Master 2D Drawing Model-Based Definition Master 3D CAD Model

4 Definitions MBD: Model Based Definition; i.e., what a design engineer creates within CAD software to express design intent MBE: Model Based Enterprise; i.e., an organization that reuses model-based definition for downstream applications and processes

5 Model-Based Environment 3D Drawing Other? Tolerance Analysis Model Automated Inspection Cost Estimation

6 What is Model-Based Definition? Also known as: Digital Product Definition Standards defined in: ASME Y ISO 16792:2006

7 What is the model? Definitions (from ASME Y ) Model a combination of design model, annotation and attributes that describes the product Design model the portion of the data set that contains model and supplemental geometry Annotation dimensions, tolerances, notes, text, or symbols visible without any manual or external manipulation Attribute a dimension, tolerance, note, text or symbol required to complete the product definition or feature of the product that is not visible but available upon interrogation of the model

8 A model includes more than geometry! Model Visible dimensions, tolerances, geometric tolerances, and notes Annotations Design Model Attributes Model geometry Parameters, material properties, etc.

9 A model includes more than geometry! Design Model + Attributes + Annotations = Model

10 Why Model-Based Definition? Establishes clear design authority ("the model is the master") Enables elimination of redundant tasks and information Enables reuse of model definition data in downstream applications and processes throughout the manufacturing enterprise

11 When will all of this happen? Enabling technology is available now Many downstream applications are available now Many companies are investigating the tools and processes now Some leading-edge companies have already begun MBE implementation DoD is pushing MBE

12 MBD and Department of Defense DoD agencies (NIST, OSD, DLA, etc.) are working to eliminate drawings from the defense supply chain NIST released MIL-STD Rev A in Feb 2013: New 3D definition for Technical Data Package Sets contract requirements for delivering technical data MBD is a contract requirement for new programs PDF (3D PDF) is preferred delivery format

DoD is shifting to Model Based Enterprise Eliminate need for 2D Drawings throughout the DOD & Supply Chain 3D Technical Data Packages: Complete Product Definition 3D Animated Work

throughout the DOD supply chain Eliminate dependency on proprietary CAD Formats Deploy complete Product Definition within lightweight 3D PDF TDPs Deploy complete Manufacturing

13 DoD is shifting to Model Based Enterprise Eliminate need for 2D Drawings throughout the DOD & Supply Chain 3D Technical Data Packages: Complete Product Definition 3D Animated Work Instructions: Complete Process Definition 3D Inspection Documents: Advanced Inspection Procedures 3D RFP/RFQ Low-Cost Procurement Dramatically reduce costs for procurement throughout the DOD supply chain Eliminate dependency on proprietary CAD Formats Deploy complete Product Definition within lightweight 3D PDF TDPs Deploy complete Manufacturing Best Practices within animated 3D PDF MBEs Allow Product and Manufacturing data to be Freely deployed on standard platforms (FREE Adobe Reader & FREE HTML5 Browsers) Slide courtesy of ANARK

14 Why the paradigm shift? Lower Cost A DLA survey showed that if a modern tech data package was provided to the supplier, it would help reduce the procurement cost of a part by almost 27% This will reduce DOD procurement costs by 27% The survey noted that suppliers would be able to reduce the cost of quoting, which accounts for 8% of the bid This will reduce supplier costs by 8% Faster Delivery The DLA survey indicated that almost 19% of supplier scrap and rework was due to poor TDP quality This will reduce scrap and rework costs by 19% 3D TDP will help streamline the creation of process plans and decrease the chances for manufacturing errors Suppliers will be able to use model data to rapidly create instructions for production operations and inspection Focused on the War Fighter Slide courtesy of ANARK

15 MBD in Creo Parametric 2.0 Annotation tools in Creo 2.0: Apply Geometric Tolerances Specify tolerances for dimensions Create 3D notes

16 GD&T in Creo Creo tools for creating geometric tolerance annotations are rudimentary No standards-based rules No automatic checking No guidance for the user Very mouse-click intensive and prone to error The tools available for creating GD&T in Creo are not sufficient for an model-based enterprise

17 GD&T Advisor An embedded Creo application Creates native Creo GD&T annotations Uses an intuitive GD&T dashboard, guaranteeing proper application of GD&T In process help to guide and educate the user Feature-centric view of GD&T Wizard-like dashboard guides the user in the correct application of GD&T Informative advisor messages to guide the user through the process Create native Creo annotations to maximize reusability

18 GD&T Advisor Benefits Supports MBD Creates annotations in the model so they can be reused downstream Fast and efficient About %75 fewer mouse-clicks required to create annotations (compared to native Creo tools) Correct and complete GD&T on the model Rules-based filters, annotation placement and validation Promotes GD&T knowledge and understanding

19 GD&T Advisor Available for: ASME Y14.5M-1994 ISO 1101:2004 and related standards A critical part of the model-based enterprise

20 MBD in Creo Parametric 2.0 Combination States A tool for managing views and annotations Defines a 3D view that is analogous to a 2D drawing view

21 MBD in Creo Parametric 2.0 Annotate Ribbon Provides functionality for defining combination states and annotations Add or delete Combination States Add annotations on specified annotation plane Manage annotations similar to the way they can be managed in a drawing

22 MBD in Creo Parametric 2.0 3D Detail options Control the appearance of 3D annotations Similar to drawing detail options for controlling drawing appearance

23 MBD and GD&T In order to fully leverage the advantages of MBD: GD&T must be applied to the model (rather than defined in a 2D drawing) GD&T must be applied in accordance with the specified tolerancing standards GD&T must faithfully represent the design requirements GD&T must by correct and complete

26 Downstream uses for MBD 3D Drawing Other? Tolerance Analysis Model Automated Inspection Cost Estimation

27 Why do we use 2D drawings? Drawings have been the "visual language" of engineering for hundreds of years Drawings provide critical manufacturing information like datums, dimensions, tolerances, etc. Until recently it hasn't been possible to express this information within a 3D environment Drawings are "easier to deal with" vs. 3D CAD models 2D TIFFs and PDFs, are smaller, easier to send, and can be opened without an expensive 3D CAD software license "Everyone" knows how to use them (2D drawings) 2D drawings (printed or electronic) can easily be redlined, reviewed, marked up, etc.

28 Why should we eliminate 2D drawings? Model vs. Drawing: Which is the master? DoD: 60% of supplier data where model and drawing don t agree Time and effort to create and maintain drawings 30% total product development budget Response times to/from suppliers much faster 50% reduction in supplier response time in MBE There are better solutions for communicating design intent...and eliminating ambiguities, scrap, rework, etc. Conclusions from NIST/US Army Supplier Survey:

29 3D Drawings Available in many formats 3D PDF Viewable in Adobe reader HTML/WebGL Viewable in modern browsers (plug-in required) JT STEP AP214 Proprietary formats (e.g., Creo View)

30 3D Drawings - Advantages Automatic creation from model Unambiguous Non-redundant data and effort Interactive query and measure tools, etc.

31 Annotation Query GD&T that has been applied with GD&T Advisor in Creo is properly associated with the applicable surfaces (in accordance with ASME Y )

34 Downstream uses for MBD 3D Drawing Other? Tolerance Analysis Model Automated Inspection Cost Estimation

35 Tolerance Analysis CETOL 6 v8.3 Import feature annotations from the CAD model Imported dimensions and gtols are linked to the related CAD annotation Linked objects automatically update (eliminates data entry and related errors)

36 Futures: CETOL 6 v9 Will read GD&T Advisor data Automate the tolerance analysis process at the part level Completely eliminates redundant effort for defining dimensions and tolerances

37 Downstream uses for MBD 3D Drawing Other? Tolerance Analysis Model Automated Inspection Cost Estimation

38 Cost Estimation MBD models include most of the data that affects part cost: Model geometry Material & other attributes GD&T & dimensional tolerances Downstream applications are available that provide accurate cost predictions

39 Downstream uses for MBD 3D Drawing Other? Tolerance Analysis Model Automated Inspection Cost Estimation

40 Automated Inspection GD&T defines quality requirements Inspection confirms whether requirements are met Downstream applications are available that integrate the CAD data (geometry and annotation data) with the inspection process

41 A complete model is required! 3D Drawing Other? Tolerance Analysis Model Automated Inspection Cost Estimation

42 Conclusions Model-Based Definition can be achieved with Creo Parametric 2.0 and GD&T Advisor Eliminating drawings in favor of MBD can result in significant savings There are a multitude of downstream uses for MBD
