Agenda

• Best Practices – recap

• Design Exploration Extension in Creo 3.0

• Demo

• Q&A

3 #PTCLiveWorx

Top-Down Design – Best Practices

4 #PTCLiveWorx

Advanced Assembly and Large Assembly Management

Is it not the same??

Not the same

But highly complementing

5 #PTCLiveWorx

• Design in Context

• Open Subset

• Lightweight Graphics

• On-demand Retrieval

Top-Down Design and Large Assembly Management

Large Assembly Management tools

Locate, filter and distribute design contexts

6 #PTCLiveWorx

• Skeletons

• Data-Sharing Features

• Reference Control

• Smart Replace

• Basic Modular Design

• Automation tools

Top-Down Design and Large Assembly Management

Top-Down Design tools

Create and iterate content efficiently and concurrently

7 #PTCLiveWorx

Simplified Representations (“Simpreps”) – short history

• Filter retrieved content

• Concurrent design in shared context

• Comprehensive drawing views and

process steps

• Fast scenery with thumbnail graphics

•

• Top-Down Design – Skeletons

Skeletons

• Central object to capture design intent – Abstract system outlines

– Common associative references

– Distribute design spaces

• Automatically excluded from Mass

calculations

• Easily identified and located

• Common uses – Geometry references

– Placement references

9 #PTCLiveWorx

•

• Top-Down Design

– Data-Sharing Features

Data-Sharing Features

• Associatively share design intent across models

• Reuse and manipulate designs of multiple objects by single parent

• Usage: – Skeleton to sub-model

– Model to model

What does it have to do with working on Large Assemblies?

#1: Level of details

Minimal Full Filtered

Skeleton-based modeling allows completing design tasks with bare-minimum required data

11 #PTCLiveWorx

What does it have to do with working on Large Assemblies?

#2: Process efficiency

Integrator / Lead designer

Integrator / Lead designer

Components designers

Distribute work with common context/intent Automate massive design changes from single object

12 #PTCLiveWorx

Motion Skeletons

• Create schematic assembly up-front

• Attach design models to skeleton bodies

• Automatically share reference geometry to

bodies and parts

• Maximize simplification and predictability

The fastest way to setup Mechanism top-down

14 #PTCLiveWorx

•

• Top-Down Design

– Reference Control

Reference Control

• Reference restrictions – Scope of creation

– Scope of selection

– References backup

• Dependency handling

• Applicable context – Global settings (Options)

– Model-specific settings (RMB / Prepare)

– Component-specific settings (RMB)

Challenges of Product Evolution

What do you do when you…

• Try out ideas for next version of

the product?

• About to perform significant

changes to a complex design?

• Evaluate different concepts for

a product design?

• Incorporate new ideas into the

“official” design?

?

17 #PTCLiveWorx

Typically these involve…

Challenges of Product Evolution

+

+

+

+

+

+

+ +

+

+

+

• Back-up and duplicate models to ad-hoc

folders… Multiple times

• Repeatedly closing/clearing session to

reload different design versions

• Take a lot of screenshots to use for

Design Review…

• Manually identify/incorporate design

changes to carry forward for “real”

What do you do when you…

18 #PTCLiveWorx

A “Sandbox” for your designs

• Snapshot entire session content

• Capture incremental changes

• Instantly toggle checkpoints

• Accept changes or revert risk-free

19 #PTCLiveWorx

Explore: Ideate – Evaluate – Decide

…

• Split to different directions

• Develop simultaneously different ideas

• Evaluate all options before making decisions

20 #PTCLiveWorx

DEX Session Content Storage

+

+

+ +

+

+

Accept checkpoint and/or save session

Content Encrypted and Compressed

Models iteration

Add models Start Design Exploration session

?

.TMZ

• Default behavior – Paths only to unmodified models

– Backup modified models only in checkpoints

• Optional setting – Full backups all models in DEX session file

• Upon Entry, Retrieval, or Manually

• Sharing with other users? – Same file system? Keep default

behavior w/o backup – Different files accessibility?

Use full backup

21 #PTCLiveWorx

Useful Operations

• Checkpoint properties

• Quick Search – Shows instant results

• By checkpoint names

• By keywords

– Shows previously searched names

– Filters tree to found checkpoints

• Review Changes – Compare to pre-modified or to other

Checkpoints

22 #PTCLiveWorx

Session content while connected to PDM

PDM Object

• Can initiate with already modified

items – Start models captured: Pre-modified

– Modified models: Entry checkpoint

• One-way download when in

active Design Exploration session – Can only upload “legit” designs from

regular session

• Store TMZ file – Design Review

– Documentation

– Revisit decisions

24 #PTCLiveWorx

• Session content to be captured in a TMU file fully

recognized as a CAD object in Windchill

• Related models and required versions will be registered

in TMU and linked as Reference objects

• Check-in TMU as regular Primary Object – Will be recognized by Windchill as Design Exploration Session

• To restore a DEX session – Download TMU

– Set dependencies to ‘All’

– Set requested versions to ‘As Stored’ (instead of default ‘Latest’)

Coming up: TMZ TMU as Primary Content

To be supported in Creo 3.0 MOR + Windchill 11.0 (X-26) onwards

FORWARD LOOKING INFORMATION SUBJECTED TO CHANGE WITHOUT NOTICE

Dec 2015

25 #PTCLiveWorx

Update Control for Advanced Assembly users

Confidently handle consequences of design change

• Intermediate update state – Data Sharing Features

• Live notifications of outdated items

• Preview changes – Before/After

– Isolate

• Selective Update

• Or explore update consequences – Can accept changes

– Or revert to entry-point

Legacy “Dependent”

Legacy “Independent” *Restorable

Break Dependency *Permanently

26 #PTCLiveWorx

Update Control for Layout users

• Entity level changes tracking

• Selective children update – Propagate to all children in one shot

– or update only some

Design Exploration Extension workflow allows

creating Checkpoints that backup only

modified and new models. Switching

checkpoints in single click – only incremental

differences are reloaded.

What’s the benefit?

Design Exploration Extension workflow

allows sharing a single compressed file and

live instant toggle of checkpoints without

data duplicates

Design Exploration Extension workflow allows

integrating only changed and new models with

a single click of accepting a checkpoint
