•Overview of wave
•Demonstration of using wave illustrated
through a case study, “COOL RIM”
•Best practices
We’ll talk about
Application of WAVE functionality:
create and control upstream flow of design
information
Our case study – ‘COOL RIM’
Techniques for die-cast tooling design process:
applied to any popular molding technology
‘COOL RIM’ – WAVE Facts
WAVE – UG/NX technology of
linking inter-part geometry
creation of inter-part dependencies
Works on part topology level
Wave Geometry Linker
Requires assembly environment
does not require WAVE control

Step 1: “as machined” model
Development of end product (as machined)
Integration of casting design intent
For effective design
‘clean geometry’
is essential
Proper file organization

What is important for successful design?
File organization: keep it simple and
straightforward
Proper and efficient use of modeling
techniques
GOOD Design Practices
Layer structure / category naming
File Organization:
Modeling tree structure –
feature sequence/grouping/naming
Expression/formula definition
GOOD Design Practices
Fixed datums and primitives: as startup features only
Modeling Techniques:
GOOD Design Practices
Fixed datums and primitives: as startup features only
Modeling Techniques:
Don’t be afraid of using sketches: avoid using
non-parametric “flying” wireframe
GOOD Design Practices
Fixed datums and primitives: as startup features only
Modeling Techniques:
Don’t multiply features: especially datums
Don’t patch model by adding features over existing ones
Don’t build deep model dependencies
Always check validity of model geometry
Don’t be afraid of using sketches: avoid using
non-parametric “flying” wireframe
GOOD Design Practices
Upfront planning investment into model and file organization
and diligence in keeping model files “clean & lean” will bring
multiple benefits to seamless flow of design information
WAVE Management
Efficient WAVE management without WAVE Control License
Vertical (serial) WAVE linking
Horizontal (parallel) WAVE linking
Managing WAVE links - breaking, reattaching, up
dating links
WAVE Geometry Linker – What are the benefits?
Full parametric integration of part design data into tooling
design process
Flexible management of linking process
“Geometry safe” method
Problem Geometry – How to deal with it?
Topology problems must be fixed – clean topology is a
Problem Geometry – How to deal with it?
Well defined and simplified parting lines
With clean part geometry, even non-parametric data
integration can proceed
Topology problems must be fixed – clean topology is a
