CAD standards Sheet numbering

[Kat]

Hi all

 

Does anyone know where I can find a list of the CAD standards for sheet numbering? (For Example E-001 would be Electrical notes.) Any ideas would be greatly appreciated.

 

Thanks!

You want a national/industry standard? Which industry do you work in?

It would be the American standard. I work at an Electrical Engineering firm.

Varies from company to company but a common one is-

 

The drawing sheet size

A0

A1

A2

A3

A4

 

then the discipline

E - electrical

M - mechanical

C - civil

A - architectural

 

then number the sheets sequentially

001

002

etc

(But they often like to start higher to make it look like they have been around longer, 3001, 3002, 3003, etc.)

 

And then add a revision letter

P1 (provisional before issue)

P2

P3

A (first approved issue)

B

C

 

so a drawing number would look something like-

 

A1M3003P3

 

A1 sheet, mechanical content, sheet No.3, third provisional issue.

 

 

 

There are lots of other ways of doing it, it depends where / for who you are doing the drawings.

We don't even have a company standard, Let alone an industry standard. Here we work with many different architects and we follow their numbering standard/preference!

A1M3003P3

 

That's a very long sheet number.

 

I would use something like this:

 

E-001 - Legends and Notes

E-100 to E-1xx - Floor Plans

E-200 to E-2xx - Enlarged Floor Plans

E-300 to E-3xx - One-Line Diagrams

E-400 to E-4xx - Details

E-500 to E-5xx - Schedules

Thanks for the suggestions everyone. I didn't know if there was an industry standard or not. We normally number ours like the last one, as a general rule. Of course civil projects and architectural projects are a little different too.
