Hi,
Is there an easy way to create layer category names corresponds to the numbers.I would like to standardize the names before I start working a new part.?
For example: Solid Parts- 1 to 10,Inter Parts- 11 to 20, Sketch- 21 to 30 etc...

I think you'll need a GRIP or ufunc program to do that. GM uses something like that for their layering. It can be done, but I don't have the licensing to do it.

Another way would be to create a seed file, with all of your preferences defined. Use this file whenever starting a new part.
 
I have seen part files that are broken up into such a system - all sketches on a certain layer, sheet bodies on their layer, solid bodies on a layer, etc etc. What is the advantage to such a system?

When I get to determine layer structure I usually group all related entities that make up a certain feature set on a layer. For instance, if I want to add a 'widget' feature, I'll put all the geometry, the extrusion (or revolve, whatever), and any necessary trim sheets on layer 'widget'. That way when I want to edit feature widget I just turn on that layer and all the necessary geometry is there.

Is it just a standards thing or does it make the file easier to edit later? If it will make life easier I'm all for it, please educate me.
 
I feel that it is much more important that catagories are used than what particular layer certain entities are on. Having said that, using a seed part can simplify the organization of the design.
I have a nasty habit of assigning catagories after I have completed the part if they are not pre-assigned, so using a seed part goes a long way in helping me overcome this self-discipline problem.
 
cowski,

It all depends on how well the categories are set up to begin with. I suppose there could actually be overkill when using categories (one sketch/layer or one set of curves/layer). I think it's just what makes sense for the product that is being designed in UG. I believe GM has a fairly decent category set up:

Solids on layer 1
Wireframe on layer 2
Centerlines on layer 3
Theoretical on layer 4
Sections on layer 5
Developmental on layer 6
Mate on layer 7

Any number of user-defined categories may exist as long as they follow a naming convention set by GM. Sometimes a user may just want to look at the geometry that was used to create the part. The user would make layer 6 visible & from there all curves, sketches & sheets or solids used to define the part are there.

I personally feel that whatever category method users are more comfortable with is the best method, rather than giving an example & claiming it to be best. I used to seperate everything on a layer of its own (like sketches) & make a category for it....but once I got used to GM's method, it really wasn't much different. However, things can become jumbled from time to time. It all depends on the complexity of the part.
