Here is my setup.
I use plan sets most of the time and have a plan set template with my pages already configured, which looks like this. Keep in mind that I do a lot of renovations and additions, and not as many new homes.
CVR - Coversheet
SITE - Site Plan
A-1 - Proposed First Floor Plan
A-2 - Proposed Second Floor Plan
A-3 - Proposed Front and Right Elevations
A-4 - Proposed Rear and Left Elevations
A-5 - Proposed Roof Plan
A-6 - Sections and Details
A-7 - Window Flashings
A-8 - James Hardie Siding Details
X-1 - Existing First Floor Plan
X-2 - Existing Second Floor Plan
E-1 - Proposed First Floor Electrical Plan
E-2 - Proposed Second Floor Electrical Plan
I name my individual drawings like this
...a1.11 proposed first floor plan
...a2.11 proposed second floor plan
...x1.11 existing first floor plan
...x2.11 existing second floor plan
and so on.
If I revise a particular drawing, I just name it as follows
...a1.12 proposed first floor plan
...a1.13 proposed first floor plan
...a1.14 proposed first floor plan (I can tell that this is the latest version because it has the highest number. I can also tell that it has been modified several times since it was started as ...a1.11)
...a3.11 proposed front elevation
...a3.12 proposed front elevation
...a3.21 proposed right elevation
...a3.22 proposed right elevation
the first two digits is the sheet number, the first number after the period tells me how many drawings are on the sheet and the third number tells me the latest revision of that drawing.
example from above, I can quickly tell that Sheet A-3 has two drawings on it (...a3.12 proposed front elevation and ...a3.22 proposed right elevation)
