Traditionally used for:
Families of Parts
Promotes best practices and standards
Design process knowledge captured in history
Inputs you edit
Inputs you edit
Design rules are:
Will Continue to be an important
Approach for Product Development
Complex example: jet engine
Parametric CAD model
Simple re-use of CAD models
“I don’t 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 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?”
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.…
Improved History Based
New History Free
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.
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 Modeling: (aka DMX, ADM, or Direct Modeling)
Families / Design Automation / Highly Engineered / Template Driven
Lightweight Designs / Small Changes / Short Lifecycle / One-off/ Manufacturing
Face Finder (Geometric)
Coaxial, Tangent, Coplanar, Eq. Radius, Symmetric
“Near” vs. “Far”
Feature Finder (Topologic)
Single, Region, Tangent, Adjacent, Feature, Rib, Slot, Boss or Pocket
Merged Rib Faces
Move, Pull, Offset, Replace, Resize Blend/Face, Delete, Local Scale
Copy, Cut, Paste, Mirror, Pattern
Group (for Feature Recognition)Design Freedom – Functional Overview
Find equal diameter
Recognize geometric conditions without regard for how the model was constructed
Face Finder – Coaxial, Tangent, Coplanar, Equal Radius, Symmetric
Maintain tangent conditions without regard for how the model was constructed
Geometry index for fast find
Distinguish near from far to alleviate over-select
Selection of topology without regard for how the model was constructed
Boss or Pocket, Slot, Rib
Option to include neighbor blends
Merged Rib Faces (very common condition)
Available in Synchronous Mode
Select a region face
Combination of faces and curves
No requirement to trim curves or subdivide faces
Additional selection methods offered directly under cursor
Both Face and Feature recognition
No need to plan ahead
Able to change methods iteratively to arrive at best selection
Uses Office 2007 mini-bar concept
Reuse of FACES
Copy Face: copy face set (scrap) for reuse
Cut Face: copy, delete from body, and heal
Paste Face: attach scrap to body
Mirror Face: combination of copy and paste
Pattern Face: rectangular or circular array
Applies geometric conditions to geometry
Applies a dimension to the model
Edit Dimension to Move Geometry
Move Geometry to Change Dimension
A mode of working with NX where linear history does not accumulate
Shell behavior without a shell feature
Walls are maintained during DMX commands
Explicit command set
Intersect model with any plane
Edit curves to change the model
Exclusive to synchronous mode
History Free … Not Feature Free
History-free does not mean feature-free
Synchronous features are recorded and editable:
Feature behavior is desirable even in absence of history
Face Finder block
Face Finder block
Suggestive selection service
Dimensional and geometric transforms
Set axis or plane via scene control
Heads-up interaction avoids visiting the dialog
Choice of Reference coordinate system
Service for reuse in commands or blocks
This is the revolution in CAD technology!!
Provides an intuitive and direct approach to design … it is simple, fast, and reliable.
NX 6 Builds on the strengths of NX 5 in Highly Engineered models
Adds a new History-Free mode
Super Easy CAD – minimal learning curve
Best of both worlds in one Package
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
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?
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
