While there has been quite a bit of discussion recently about our synchronous technology in the history-free modeling mode,  I’d like to share how it can also be used in the history-based modeling mode in NX’s Design Freedom tool set.
If you’re a CAD user, you’re probably familiar with history-based modeling.  You create a model from a base feature by adding and subtracting other features.  Features are added in a linear fashion and stored in a history tree (sort of like a recipe).  Modifying the model usually requires a fairly detailed understanding of how the model was built.
 
In this video, you need to change this eight-year-old fully parametric part, and its associated drawings.  The history tree gives you an understanding of how the part was originally built.  Your task is to modify a pocket and maintain the model history.  This may seem like a simple task, just adding two dimensions.  However, when the original designer created the model, he didn’t anticipate this change and there is a feature in the models history that interferes with your change. So how do you quickly make the change, and keep the model’s history intact?
 

As you can see, NX in the history-based mode preserves your history-based design while giving you access to the new synchronous modeling commands.  That’s why we call it “Design Freedom”!
 
If you’d like to learn more about the commands in the NX Design Freedom tool set, take a look at a recent review in MCADCafe of NX 6 by Jeff Rowe or let me know what questions you have.
