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 ?
Complex example: jet engine
Challenges of History Based Systems
“I don’t know how this
model works.”
Parametric CAD
Where we get stuck…
model
“I need to make a oneoff change to a model
from an OEM”
Simple re-use of
CAD models
“I made this last year,
and I don’t 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 I’ve found a
good model… Now
what do I do with it?”

Benefits of Synchronous Mode

Performs best for
“Unplanned Change”
•Edit B-rep data received from another CAD system
•JT, STEP, IGES, CATIA, SolidWorks, Pro/E, etc…

Design knowledge is
added to the model
•One time change or What-if Design

Extremely easy to
use
•History tree difficult to understand
•Modifying parametric design is costly
•Translation is not viable

Increased capacity
for “what if” design
studies
NX provides tools to add intelligence to the model.…

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.

Synchronous Modeling

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 models—without 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.

Synchronous Modeling: (aka DMX, ADM, or Direct Modeling)


History Mode: (aka Parametric 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 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 historyfree 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
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
