reset layer settings
reset layer settings
(OP)
I'm often fighting the problem with layer settings in parts and from components-- foreign data from colleages and co workers. To explain. the problem: the annoyance is the layer setting controlled from geometry in the parts can be different in display and assembly part( our components are added on original layers -by default). Example - when I move a sketch from a component (referenceset entire part) to a layer its not the same layer setting in display part of the component. I think this should be no difference - but this has a long history in UG and will never be fixed
. Question is how to reset ? How do you tackle this problem.

RE: reset layer settings
The thing that you have to remember when 'working in context' is that it's the Displayed Part which controls how objects look, including which Color table to use AND which layers are visible or not. So even if you save the Component's part file with the Sketch layer invisible, if you use the Entire Part Reference Set in the Assembly and the Assembly's Layers are set as Visible, the layers of the Component will be as well.
The problem with Layers is that while every object has a Layer assigned to it, the status of that Layer is owned by the Part File itself and in the case of an Assembly, the Displayed Part.
Note that the best practice that has evolved over the years has been to depend more and more on Hide/Show (Blank/Unblank) and the use of Reference Sets to act as filters (remember, objects which are NEVER loaded into the Assembly can NOT have their Layer status mis-assigned). The advantage of Hide/Show is that this status is owned by the objects themselves and cannot be overridden by the Assembly unless you explicitly do that on an object by object basis.
Anyway, I know that this doesn't really help with your current situation, but perhaps it will help you establish some best practices going forward which will make these problems less of an issue in the future.

RE: reset layer settings
IMHO layers are not that problem - I should be that when I move geometrie from assembly level of the component it should also move on the same layer in the display part - where is the problem? Everybody is happy and the layering will be more controlable - no mismatch. Would improve the usabillity of NX very strong. Btw I don't like those improvements were made in all situation with internal sketches.
RE: reset layer settings
The real issue is that Layers are a bit of a legacy concept inherited from the earliest days of CAD. Back in 1977, when I first stated to use Unigraphics, we had only 31 layers which had just been enhanced from 14 and which was increased to the current 256 in 1978, and except for Categories and User Interface changes, they have not evolved in any significant way since then. In fact, most newer systems on the market today don't even have anything which could even be called a 'layering' scheme.
Unfortunately, layers are not always compatible with some of today's functionality, such as assembly modeling, particularly when 'working in context'. Long term, we need some different tools and behaviors, some of which we are slowing implementing, but people have to change their workflows and take advantage of what we are doing so that they can get the most out of the software and limit the places where these legacy issues crop-up.

RE: reset layer settings
I have done some other cad - layers are Ok IMHO not old fashion - but they had never really had been reviewed in assembly modelling as you said - that is even the same with referencesets most users hate them because layer or ( filtering) model referencesSets on assembly level makes Nx not very easy to use. Sometimes fewer options are straight ways ...
RE: reset layer settings
I know this may sound obtuse and even a bit trivial, but anything which makes it easier to understand why and when I use a particular function and what benefit I can expect from it, such as Reference Sets, can only be positive. After all, you just said it yourself, "Sometimes fewer options are straight ways..." and we believe that as well.
Philosophically, I agree with all that you've said, but I also believe that we are providing the better tools and that you really need to leverage what's already there and to get onto the preferred 'path' as this is where the investments are being made and where we expect the future ones to come into play as well.

RE: reset layer settings
I must apologize in nx7.5 there is an option to inherit the seeting into the owning part - in object display -
cool
