Detail Sheet Numbering System

I've seen detail sheets number 1,2,3... for each page they're one. I've also seen details numbered 123... for page one and then continue 456... on page two, 789... on page three.

Any thoughts on the pros/cons to continue the count past each page or not. Seems like you would have a unique number for each detail, but revisions could be a pain if adding/subtracting detail numbers was not accounted for.

1,2,3 each page, starting at the bottom right corner, increasing up, then left in a grid, skipping numbers where a drawing takes up more than one grid space.

That's how I was taught to do it and how I've always done it. The idea being that sheets which aren't completely full have most of their information to the right-hand side of the page, and the numbering starts by the page number.

detail numbers should start back at 1 for each sheet... and as much as possible, be placed in the same clock or counterclock fashion throughout the entire project.

I see only cons with detail numbering that spans multiple drawings.

We start with detail 1 on each new sheet.  We also use a numbering system so A5.1.1 means "5" (details) point "1" (1st sheet) point 1 (1st sheet in series).  It's also as much as possible it corresponds to the location.   Think chapter and page references.

Example A4.1 would have a few wall sections.  A5.1.X ("x" being whatever page in the series) would have the details from those wall sections found on the 4.1.

Also works from right to left/top to bottom in a stacked fashion.  So you might have 5 wall sections on that A4.1.  Wall section 1 would be on the right; And the first sheet in the series would have the details associated with it.

I put them in a grid, labeled by letter and number. Upper left is A1/A7.0. Bottom right is D4/A7.0. This is for a 24x36 sheet. Some people can fit 5 columns & rows on a 24x36 but I do 4. The grid really helps lay out sheets fast.
