As to the question, could you point to a definition of what you are looking for? I am unfamiliar with the terminology "layer associated a Polyline Great".

I have 2 polylines im my dwg , one inside other.

In LISP i find the Small polyline.

How to get the value assigned to the layer PolyLine Great through LISP, using as a basis the small polyline?

Using as a base the image that I published, it's like a group the largest has the smallest Polyline.
So if I have little control polyline, how to know through LISP which the polyline large, and thus take the value of the same Layer?

I publish in top of posts, an example in JPG

So you have in mind AutoLisp & AutoCAD?
=> This belongs to Other dialects.
And you want to get a circumferential/parental/outer polyline of inner polyline, right?
