FLEXIBLE MODELING AND YOUR PRODUCT DESIGN PROCESS
“unexpected last minute changes”
What is the problem ?• Unexpected changes on complex parametric models are painful due
to parent/child relationships
• Need to understand design intent before making modification
• A lot of time spent for recreating and rebuilding geometry.
Negative consequences• CAD model modification on the critical path or not performed.
• Waste of time to delete and rebuild geometry to implement
changes.
• ……. Delayed projects and lost of productivity
“38% of organizations say they experience dramatic or
multiple last-minute changes1”

FLEXIBLE MODELING AND YOUR PRODUCT DESIGN PROCESS
Flexible modeling for “unexpected last minute changes”
Solution highlights• Pure geometric approach of modification
• No consideration of existing design intent and features, even on
very complex models
• No parent/child issues even in case of geometry removal
• Original design intent redefinition (pattern vs symmetry)
• Changes are captures in model history as parametric features
Benefits• Rapid implementation of design changes to speed product design
and development.
• Eliminate wasted time and effort performing non-value added
activities and recreating existing geometry.
• …..… Reduce product development costs and time to market

“imported data modification”
What is the problem ?• Imported data is a “dead geometry” with no features, no history and
no dimensions.
• Limited tools to work with and edit multi-CAD data.
Negative consequences• Difficulty collaborating and sharing data with suppliers, partners
and the extended design team.
• Design reuse and update is very difficult
• Rely on third party CAD application
• ……. Delayed projects and lost of revenue and profitability
“59% of organizations say modifying models from other 3D
CAD systems is difficult”

Flexible modeling for “imported data modification”
Solution highlights• Pure geometric approach of modification make possible changes
on imported models (dead solid resurrection)
• Automatic design intent recognition capabilities
• Modifications stored as editable parametric features in model
history
Benefits• Leverage data from other CAD systems
• Facilitate the effective reuse and repurposing of CAD data from
any source.(Variant design, simplifications, optimization …)
• Support The “CAD Harmonization process”
……. Reduce Time-to-Market and Reduce Development Costs

Simplifly models for “simulation”
What is the problem ?• Models simplification is difficult due to parent/child relationships
• Design intent and strategy is often a problem for analysts
• creo Skills are often required to perform simplifications.
• Design changes for optimization are difficult
Negative consequences• Analysts may rely on Mechanical designers to perform models
simplification
• Time spent for simplification leaves less time for engineering and
innovation.
• Lack of modeling flexibility limits design optimization.
• ……….. Increase time to market, less product quality.
53% of organizations say their 3D CAD tools are too
difficult for non-expert or casual users1

FLEXIBLE MODELING AND YOUR PRODUCT DESIGN PROCESS
Flexible modeling to “simplifly models for simulation”
Solution highlights• Pure geometric approach of modification
• Powerful direct modeling features to simplify and modify geometry
• No need of parametric design skills to make modifications
• No parent/child issues even in case of geometry removal
• Make modifications without considering model history
• Define “design variables” for optimization
• Design model not altered, changes are captured as additional
parametric features in model history.
• Same process for Creo parametric native data and imported data
Benefits• Analysts don’t rely anymore on Mechanical designers to perform
models simplification.
• Mechanical designers can focus on Design activities
• More freedom and efficiency to optimize models geometry.
• …..… Reduce product development costs, increase product quality

IN SUMMARY …..
“Before” scenario
• Difficult to manage last minute changes on complex
Creo parametric models
• Impossibility to modify imported data for downstream
reuse
• Struggle with simplification and optimization processes
for simulation
“After” scenario
Easily work with and make changes to non-PTC data from
suppliers, partners and extended teams.
Make fast, flexible edits to “rigid” parametric models with
obsolete design intent.
Directly edit and evolve CAD data for design reuse and
repurposing.
Easily simplify and prepare CAD geometry to support analysis and
downstream processes.
