AutoCAD - Layer Names and Structure

LAYER STRUCTURE:
The Layer structure at TBG has been organized according to, type of drawing (category), topic (sub-category), and detailed topic (sub-category descriptor), and/or scale specific items. This layering system is a hybrid of our previous system of layering and the AIA standard. The AIA layering standard would have all of our layers starting with "L". The naming structure looks like this:

LAYER NAME & DESCRIPTION
0S-walk-bldr-The first two letters “0S” designate the Classification of the layer
0S-walk-bldr: The next four letters designate the Division. ** The Division should not exceed 4 letters
0S-walk-bldr: The next item we can call the Sub-Division. ** The Sub-Divisions should not exceed 4 letters
0A-note-A-0010: “A” is the Category for that note. There are categories A,B, and C.
0A-strt-0010: ”0010” is the Scale in which that item was drawn. Any layer that has the scale at the end of a layer name is typically called a Dimscale Layer.
