• NX 6 Design Freedom with Synchronous Technology

Design Freedom Powered by Synchronous Technology

• With Synchronous Technology, you can create
  designs in a natural way. Theres no need to
  pre-plan designs, or spend time worrying about
  the models future use. The results up to 100
  times faster design experience for many
  activities.
• With Synchronous Technology, design reuse doesnt
  have to mean remodeling. Anyone can change any
  model regardless of who created the original,
  without having to unravel and debug how it was
  built. The result Engineering Change Orders in
  seconds that wouldve taken hours.
• With Synchronous Technology, designers can easily
  access and edit models created in any CAD system,
  regardless of the design methodology. Synchronous
  Technology enables even occasional users to edit
  CAD data from other systems FASTER than the
  original system can!

Benefits of History Based Systems

• Traditionally used for
• Families of Parts
• Design Automation
• Highly Engineered
• Template Driven
• Promotes best practices and standards
• Design process knowledge captured in history
• Features
• Relationships
• Formulas

• Inputs you edit
• Diameter, D
• Output
• All holes update

Trivial example

• Inputs you edit
• Air flow volume
• Number of stages
• RPM
• Output
• Compressor design
• Design rules are
• Highly complex proprietary
• Exactly the type of information you do not want
  to share with other companies ?

Will Continue to be an important Approach for
Product Development

Challenges of History Based Systems
I dont know how this model works.
I need to make a one-off change to a model from
an OEM
Where we get stuck
I made this last year, and I dont remember how
it works.
The designer who made this retired last month.
?
It will take me longer to figure out than it
will take me to recreate it.
I think Ive found a good model Now what do I
do with it?

Benefits of Synchronous Mode

• Performs best for Unplanned Change
• Design knowledge is added to the model
• Extremely easy to use
• Increased capacity for what if design studies

• Edit B-rep data received from another CAD system
• JT, STEP, IGES, CATIA, SolidWorks, Pro/E, etc
• One time change or What-if Design
• History tree difficult to understand
• Modifying parametric design is costly
• Translation is not viable

NX provides tools to add intelligence to the
model.

Design Freedom The Best of Both Worlds
7
Terms

• Design Freedom
• Design Freedom is a set of new modeling
  technologies in NX focused on increasing your
  productivity by eliminating CAD system overhead.
• Design Freedom enables you to focus on designs
  instead of the CAD system.
• Design Freedom is powered by Synchronous
  Technology, a new modeling engine developed by
  Siemens PLM Software.

• Synchronous Technology
• Synchronous Technology represents a way to
  interact much more efficiently and intuitively
  with modelswithout being confined to the way
  models were originally constructed.
• This new approach to modeling instantaneously
  synchronizes engineering relationships,
  features, and parameters through a more direct
  interaction paradigm. The result is a design
  methodology without limitations.

8
Terms

• Synchronous Modeling (aka DMX, ADM, or Direct
  Modeling)
• Synchronous modeling is an approach for design
  change with emphasis on modifying the current
  state of a model without regard for how the model
  was constructed, its origins, associativity, or
  feature history. The model could be imported,
  non-associative, with no features, or a native NX
  model complete with feature history.

• History Mode (aka Parametric Modeling)
• History Mode is a design mode that builds and
  replays a global feature tree. This design mode
  is optimal for designing highly engineered parts
  that undergo complex changes that can be planned
  for during design creation. In history mode
  synchronous modeling operations are recorded as
  features in the history tree and are replayed
  along with the tree.
• Synchronous Mode (aka History-Free mode)
• Synchronous Mode is a design mode that builds
  local features and dimensions, but does not
  replay a global feature tree. This design mode is
  optimal for parts that undergo rapid changes that
  cannot be planned for during design creation. In
  history-free mode synchronous modeling operations
  are created as local features, persistent
  dimensions, and constraints.

Frequently asked Questions

• Is this an additional module?
• No, this is a core part of NX Modeling There
  is no additional license for this functionality
• Can this be used with applications such as
  MoldWizard?
• Yes, we see the direct tools working very well
  as part preparation tools for manufacturing
• Does this work with Product Template Studio?
• If a customer is developing a template part
  they will have more control if they use
  parametric history
• However, if a customer imports data and adds
  dimensional edits the expressions created can be
  accessed by PTS making the imported part a
  template
• Are we forcing our customers to learn a new
  approach?
• No, with NX we are continuing to develop the
  best of both worlds we see customers where
  parametric modeling is a key part of their
  process, we also see customers who do not worry
  about history, NX delivers best of both approaches

32
Frequently asked Questions

• Can this work with JT data?
• It relies on a solid model, if the JT data
  contains XT B-Rep this will be edited.
• Is this a separate file type?
• No
• Do my customers have to translate their data?
• If your customer has models that they are
  already using there is no need to make them
  history free unless they really want to.
• If they want to get the power of the editing
  offered by Design Freedom they can and that is
  using the power of synchronous technology
