Design Freedom Powered by Synchronous Technology With Synchronous Technology, you can create designs in a natural way. There’s no need to pre-plan designs, or spend time worrying about the model’s future use. The results: up to 100 times faster design experience for many activities. With Synchronous Technology, design reuse doesn’t 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 would’ve 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 ? 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 model Simple 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 NX provides tools to add intelligence to the model.…

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. History Mode Synchronous Mode Synchronous Modeling Design Freedom Synchronous Technology 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 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
