Split a drawing set into named sheets

Drop a 300-page set. Get one PDF per sheet, named from its own title block: A-101, S-201, M-301. Nothing is uploaded.

How it works

Step 1

It reads the title block

Not the whole page. A floor plan is covered in room numbers and detail callouts that look exactly like sheet numbers, so only the title block strip is searched.

Step 2

It matches the number by shape

Discipline letter, then level and sequence: A-101, S-201, FP-101. Matched by pattern rather than against a list, because every office invents its own.

Step 3

You check, then split

Every page is listed with the name it will get. Pages whose title block could not be read are shown as such rather than guessed.

What it handles

Why splitting by page number is not enough

01

Room numbers are decoys

A floor plan has "101" and "3/A-501" printed all over it. Any tool that scans the whole page picks one of those instead of the sheet number.

02

Title blocks move

Usually the right-hand strip on a landscape sheet, sometimes the bottom. Both are checked, and portrait sheets use different proportions.

03

Disciplines are how sets are filed

The letter identifies the trade, so the summary tells you how many architectural, structural and MEP sheets the set contains.

04

Order is preserved

Filenames are prefixed with the page number by default, so the folder reads in set order rather than alphabetically.

Questions

How big a set can it handle?

Up to 200 MB, which covers most full sets. The whole file is held in your browser’s memory, so a very large set on an old laptop will be slow before it fails. Splitting a set in halves works if you hit that.

What if the sheet numbers are wrong?

Every page is listed with the name it will get before anything is split, so you see the mistake rather than finding it later in a folder of 300 files. Anything unreadable keeps its page number instead of being guessed at.

Does it work on a scanned set?

Not directly. A scan has no text layer, so there is no title block to read. Text recognition can add one, but recognized digits are the most likely thing to be misread, and a wrong sheet number in a construction set is a real problem. Splitting by page number still works.

What about revision clouds and addenda?

It reads the number printed on the sheet, so a revised A-101 comes out as A-101. If you are splitting two revisions of the same set, split them into separate folders.

Is the set uploaded anywhere?

No. A drawing set is often confidential before bid, and this one never leaves your computer. Load the page, disconnect from the internet, and the split still works.
