CAD Standards – Sheet Numbering Ideas

Sheet Numbering and Layout Ideas

Many firms have standard ways of numbering sheets in a set – here are my favorites.

Details

The numbering of the details should be done per the project standard provided by the Project Manager.

Details are typically designated “1” “2” “3”, etc.

Plans, Elevations and Sections

Plans are designated “1” “2” “3”, etc.

Elevations are designated “1” “2” “3” and so on

Sections are designated “A” “B” “C” and so on.

Interior Elevations are designated with a combination of number and letter. 1A, 1B, 1C, 1D with the “A” elevation as the North wall and proceeding clockwise (B is East, C is South and so on.)

Layouts

Laying out sheets can have a pattern also…

Details

The sequence for inserting the detail onto the detail sheet shall begin at the lower right-hand corner of the drawing area adjacent to the title block and then proceeding from bottom to top and across the sheet from right to left.

Details larger than one module may be inserted in the sheet by encompassing as many contiguous drawing modules as required by the size of the detail. Only full drawing modules shall be used. No fractional portions of modules shall be allowed.

Plans, Elevations and Sections

Each of these types of plans are placed on the sheets starting in the lower right corner and move up. They will take as much area as needed to the left and return to the bottom of the page and go up.

There is no requirement for the layout of Plans, Sections and Elevations to fit within the grid modules.
