8. SUMMARY

Reviewed concepts of:

• Profiling
• 3D from profiles
• Features
• Assembly design
• Detailing from the 3D model

Hope you:

• Understand the concepts
• Are in better position to evaluate or use CAD/CAM systems

WHAT TO OBSERVE IN A VDD SYSTEM

Sketch and part "connection" techniques

Explicit modeler

How variable and constriants drive the models

Model change connected to drawings

Variational - 2D or 2 1/2 D

History based - 3D

Feature based

3D from connected profiles

Automatic parameterization

Assembly Modeling

Application associativity

FUTURES

Expect systems to evolve

Reusable parts based on design variables and features

Application advances

• Design optimization
• Automated "generative" NC
• Better assembly of parametric parts

Easier to use systems?
