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.

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

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. 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. 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. 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. USE
THE STANDARD LIBRARIES
• Use them
• Have a written process plan to update and maintain
www.action-engineering.com 17

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. 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
