Top-Down Design – Best Practices
#PTCLiveWorx

Advanced Assembly and Large Assembly Management
Is it not the same??
Not the same
But highly complementing
#PTCLiveWorx
4
Top-Down Design and Large Assembly Management
Large Assembly Management tools
• Design in Context
• Open Subset
• Lightweight Graphics
• On-demand Retrieval
Locate, filter and distribute design contexts
#PTCLiveWorx

Top-Down Design and Large Assembly Management
Top-Down Design tools
• Skeletons
• Data-Sharing Features
• Reference Control
• Smart Replace
• Basic Modular Design
• Automation tools
Create and iterate content efficiently and concurrently

Features
and

• Filter retrieved content
• Concurrent design in shared context
• Comprehensive drawing views and
process steps
• Fast scenery with thumbnail graphics

Skeletons
•
• Central object to capture design intent
– Abstract system outlines
– Common associative references
– Distribute design spaces
• Top-Down Design
– Skeletons
• Automatically excluded from Mass
calculations
• Easily identified and located
• Common uses
– Geometry references
– Placement references
#PTCLiveWorx
8
Data-Sharing Features
•
• Associatively share design intent across models
• Reuse and manipulate designs of multiple objects by single parent
• Usage:
• Top-Down Design
– Data-Sharing Features
– Skeleton to sub-model
– Model to model

What does it have to do with working on Large Assemblies?
#1: Level of details
Skeleton-based modeling allows
completing design tasks with
bare-minimum required data

Motion Skeletons
The fastest way to setup Mechanism top-down
• Create schematic assembly up-front
• Attach design models to skeleton bodies
• Automatically share reference geometry to
bodies and parts
• Maximize simplification and predictability
#PTCLiveWorx
12
Reference Control
•
• Reference restrictions
– Scope of creation
– Scope of selection
– References backup
• Dependency handling
• Top-Down Design
– Reference Control
#PTCLiveWorx
• 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?

Challenges of Product Evolution
What do you do when you…
+
+
+
+
+
+
+
+
+
+
+
+
Typically these involve…
+
• Back-up and duplicate models to ad-hoc
folders… Multiple times
• Take a lot of screenshots to use for
Design Review…
• Repeatedly closing/clearing session to
reload different design versions
• Manually identify/incorporate design
changes to carry forward for “real”
#PTCLiveWorx
17
A “Sandbox” for your designs
• Snapshot entire session content
• Instantly toggle checkpoints
• Capture incremental changes
• Accept changes or revert risk-free
#PTCLiveWorx
18
Explore: Ideate – Evaluate – Decide
• Split to different directions
• Develop simultaneously different ideas
• Evaluate all options before making decisions

and/or save session
?
Content Encrypted
and Compressed
• 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
#PTCLiveWorx
.TMZ
• Sharing with other users?
– Same file system? Keep default
behavior w/o backup
– Different files accessibility?
Use full backup
20
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
#PTCLiveWorx
21
Session content while connected to PDM
• 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

Coming up: TMZ TMU as Primary Content
Dec 2015
To be supported in Creo 3.0 MOR + Windchill 11.0 (X-26) onwards
• 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’)
#PTCLiveWorx
FORWARD LOOKING INFORMATION SUBJECTED TO CHANGE WITHOUT NOTICE
24
Update Control for Advanced Assembly users
Confidently handle consequences of design change
• Intermediate update state
– Data Sharing Features
• Live notifications of outdated items
Legacy “Dependent”
Legacy “Independent”
*Restorable
Break Dependency
*Permanently
• Preview changes
– Before/After
– Isolate
• Selective Update
• Or explore update consequences
– Can accept changes
– Or revert to entry-point
#PTCLiveWorx
25
Update Control for Layout users
• Entity level changes tracking
• Selective children update
– Propagate to all children in one shot
– or update only some

Iterations
DEX allows exploring x7 more

Design Exploration Extension workflow allows
creating Checkpoints that backup only
modified and new models. Switching
checkpoints in single click – only incremental
differences are reloaded.

Design Exploration Extension workflow allows
integrating only changed and new models with
