NX7.5 2D drafting Dimension associativity

[SDETERS]

We are migrating from I-Deas to NX7.5 I am now doing my first real drawing with dimensions and text. Is it better to use the "model" reference set and dimension to the Features Edges, Surfaces Ect. Or is it better to use the "entire part" reference set to associate our 2D dimension to the reference geometry that we made those features from? Which method is more robust to keep dimension from losing associativity? I Started using the "entire part" reference set, but when I switched the reference set back to model all of my dimensions lost associativity

Thanks

When you create a Master Model Drawing, the system defaults to the 'Model' Reference Set for a reason.

To an Engineer, the glass is twice as big as it needs to be.

There is many setting that NX defaults to. I did not know if one way was prefered over the other. So Model Reference set it is. Thanks

Not a wealth of reference set experience here....and what experience I do have with them wasn't used to control the context of the display of the geometry in drafting - it was used to display BREPS (faceted models) of components when working on gigantic assemblies with many components.

Unless I've got a centerline that is almost impossible to define with Utility Symbols, I've always dimensioned to model edges and faces rather than reference/construction geometry.

You could feasibly remove all parameters and then remove all reference geometry from a model and completely blow up all dims on a drawing - using model edges and utility symbols would more than likely keep that from happening.

I'm sure other users might have different approaches - just my experiences and preferences.

And as of NX 7.5 there is NO longer any need to use Reference Sets to manage lightweight representations in a large, or for that matter, any size assembly.

Not doing so by choice - customer requirement.
