Drawing Numbering System

[jacksona]

I was hoping for a Poll on drawing numbering convention

We are a Building Services Company & are currently tweaking our CAD Standards.



Any ideas so we can discuss ?

When you say 'drawing numbering' are you referring to file naming and numbering, or hard-copy sheet numbering?

Presuming the latter, the I don't think you can do better in the AEC world than the Uniform Drawing system from the Construction specification Institute, which is part of the National CAD Standards. Works well for multi-discipline jobs, and is adaptable to Civil site work. Not a good fit for roadway design, since whichever state you're in will want their DOT conventions.

If you mean drawing sheets, I would suggest using A-100, A-101, A-102, A-201, A-301, A-401.

I agree with Cadtag (obviously, just look at my sig). The NCS covers sheet naming quite well, and leaves very little for guessing. The best part is when we work with subs, and they whine about how we name sheets, we remind them its the NCS. For the most part, that stops them.

Yes NCS is the way to go.

discipline-drawing type-number in series

0= GENERAL
1= PLANS
2= ELEVATIONS
3= SECTIONS
4= LARGE SCALE VIEWS
5= DETAILS
6= SCHEDULES & DIAGRAMS
7= USER DEFINED
8= USER DEFINED
9= 3D REPRESENTATION

A-101 first architectural plan drawing
A-201 first architectural exterior elevation

S-501 first structural detail drawing

...and so on

A-100 wouldn't exist in NCS as the first sheet will always end in "01"

Thanks for the tip...

You actually can have 100 sheets in the NCS. If you need a general note sheet, or a cover sheet for a subset, you would probably call it a 100 sheet. The only restriction is that you cannot start the deisgn on 100 sheets.

Don't forget too that you can double up your drawing discipline codes. When we utilize a particular geotechnical engineer to design a segmental block wall for us, I place his sheets on a LB-501 sheet. L is for Landscape since we're an LA firm, and B is for geotechnical.

Really? I wasn't aware of this, I stand corrected then.
Where can I find this information? We the have NCS 3.1 book, I'd like to look that up and get more info about it.

Yes, we sometimes utilize the level 2 designator as well, like AD-101 (architectural demolition plan) or CS-101 (civil-survey plan) and so on.

Man oh man! Time for an upgrade to NCS 4

D is now used for process and S is for structural. I never used 3.1, but from the footnotes I've seen in 4.0, they really cleaned up and simplified things.
