I am using NX11 and TC 10.
I have added few assemblies consisting of 100's of componentes in DRAWING specification, but when I am adding the BOM it is selecting all the parts from the navigatior. I am not able to make the components as REFERENCE ONLY because it is hidden. How to activate the option of "Component is Reference - only" in drafting environment.
you can also set an attribute in the part properties to ignore in parlist.
You cannot make a 'component' one-level-down from the specification a Reference Component. Add the assembly to your master model as a component and you will be able to use this option.
