How to create CAD designs to facilitate collaboration and inter-operability between designers and the rest of the team. Designers, often trapped by looming schedules and inadequate process, need tools to fulfill the demands of collaboration and inter-operability. This presentation will address a set of simple standards and processes that allow designers to include necessary data and modeling standards directly in their CAD models. They are quick and clear instructions that capture the information required by the entire team. This strategy facilitates collaboration among team members such as analysis, parts and materials, manufacturing and configuration management.

CAD MBD & 3D Technical Documentation

  1. 1. www.action-engineering.com 1
  2. 2. Save Millions, Use 3D DOCUMENTATION From Bearing Installation to Airline Seat Repair QuickTimeª and a H.264 decompressor are needed to see this picture. Jennifer Herron www.action-engineering.com 2
  3. 3. AGENDA • The Test • 3D Via Composer • How Designers Fit into Model Based Design • Implement • Savings www.action-engineering.com 3
  4. 4. The Test… www.action-engineering.com 4
  5. 5. Time Yourself… How long does it take you to figure out what this is? Courtesy of Brice Manufacturing, Inc. www.action-engineering.com 5
  6. 6. 3D VISUAL INSTRUCTIONS Legrest De-Activation QuickTimeª and a H.264 decompressor are needed to see this picture. Courtesy of Brice Manufacturing, Inc. www.action-engineering.com 6
  7. 7. 3D VISUAL INSTRUCTIONS Automates Transfer Process Enhances Comprehension of from CAD to CMM Illustrations Assembly and Instructions www.action-engineering.com 7
  8. 8. 3D VIA COMPOSER • Imports any CAD File Type QuickTimeª and a decompressor are needed to see this picture. • Publishes to Standard Formats • Update with latest CAD • Created for non-CAD users to implement Support Customers and Vendor File Formats www.action-engineering.com 8
  9. 9. WHAT IS THIS DOING? Communicate… Collaborate… Interoperate… www.action-engineering.com 9
  10. 10. WHY? Model Based Design Cycle Model Based Design (MBD) Designer • CAD must be MBD compliant Materials/Process Analyst • More Efficient • Work Instructions from original Checking Systems 3D CAD 3D Model Database Assembly/Test Config Mgmt CAD Models are the Design Authority Manufacturing Procurement www.action-engineering.com 10

  12. 12. COLLABORATION & INTEROPERABILITY www.action-engineering.com 12
  13. 13. DESIGNERS WHAT DO YOU DO? • MAKE 3D models the deliverable • FOLLOW the CAD part and assembly modeling standard • USE Standard Part Libraries • MAINTAIN Your Models www.action-engineering.com 13
  14. 14. MAKE CAD THE DELIVERABLES • Ignore that the drawing is the final product • Forces you to do the detailed design (GD&T) in the model, not after your done with it • Part & Assembly Nomenclature must match the drawing tree • Create Full Featured Models – Follow the standard – Fillets, Chamfers – Nominal vs. Min/Max Dimensioning – Standard Hole Sizing www.action-engineering.com 14
  15. 15. MAKE GOOD ASSEMBLIES • Fully Define It – Assembly hierarchy must follow the drawing tree – Mate each component in all 6 Dimensions • Create Low Fidelity Model • Create High Fidelity Model • Create Stowed & Deployed Configurations • Apply to every assembly www.action-engineering.com 15
  16. 16. FOLLOW THE CAD STANDARD • Must have a CAD Modeling Standard – Part and assembly modeling standard • Just make one – Change it as you need to • Write a process plan to change the standard www.action-engineering.com 16
  17. 17. USE THE STANDARD LIBRARIES • Use them • Have a written process plan to update and maintain www.action-engineering.com 17
  18. 18. MAINTAIN YOUR MODELS • Have a written process plan • Make change to the model only – Drawing flows from CAD only – No faking on the drawing • Manage changes as you go – Don’t let the redlines build up www.action-engineering.com 18
  19. 19. DESIGNERS WHAT SUPPORT DO YOU NEED? • Setup Roles/Responsibilites – Match Drawing Tree • Master Modelers – Responsible engineers assigned to each assembly – Top/Master Modeler controls integration and updates to top assembly • CAD Checkers – Directly check the models www.action-engineering.com 19
  20. 20. DESIGNER ADVICE Think beyond the engineering Over communicate Change the way you view your documentation www.action-engineering.com 20
