We are taking delivery of a new turret punch machine in the new year and we would like to explore how to create a degree of associativity between a part and it's flat pattern dxf so that the two files are always "in step".
Not sure if this is best managed through workflow or via some other method.
The desired end result is that dxfs always reflect the features from their parent model, even when these models are revised.
Malcolm,
Once dxf's are created they are no longer associated with the file they come from.
This holds true for any exported type file.
What I can suggest is looking into something called the design binder.
