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 ?

Complex example: jet engine

Will Continue to be an important

Approach for Product Development

Challenges of History Based Systems

Where we get stuck…

“I don’t know how this model works.”

“I made this last year, and I don’t remember

how it works.”

“It will take me longer to figure out than it

will take me to recreate it.”

“The designer who made this retired last

month.”

“I think I’ve found a good model… Now

what do I do with it?”

“I need to make a one-off change to a model

from an OEM”Parametric CAD

modelSimple re-use of

CAD models

??

•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

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

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.

SynchronousTechnology

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.

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 ModelingThere 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
