Use case — Revision updates
Update revision text across multiple AutoCAD drawings
A drawing package moves from Rev A to Rev B. ISSUED FOR REVIEW becomes ISSUED FOR CONSTRUCTION. A superseded revision note has to change across dozens or hundreds of sheets.
Instead of opening each DWG in turn, apply the same revision-text rules across the whole drawing set in one batch — and get a line-by-line report of what changed.
- One rule set, the whole package
- Audit report of every change
- Measured dimensions untouched
- No AutoCAD installation required
One revision change, repeated across an entire set
Revision updates are simple changes. The problem is repetition. A project set might need:
| Find | Replace with |
|---|---|
| REV A | REV B |
| ISSUED FOR REVIEW | ISSUED FOR CONSTRUCTION |
| PRELIMINARY | FOR CONSTRUCTION |
| 15 JUL 2026 | 27 AUG 2026 |
| STANDARD ABC-2021 | STANDARD ABC-2026 |
The rules take seconds to write. The expensive part is opening, finding, editing, saving and checking every drawing individually. That part is what a batch removes.
Where revision text is actually stored
Revision information is rarely just visible single-line text. Depending on the template it can sit in any of these:
- Title block attributes
- Revision number, issue date, drawing status and approval information held as block attributes — the commonest case by a distance.
- Plain TEXT
- Simple revision marks and issue notes.
- MTEXT
- Longer revision descriptions and issue notes.
- Paper space layouts
- Revision information repeated in each layout's sheet title area.
- Tables
- Revision history tables and drawing schedules.
- Block definitions
- Repeated drawing information embedded inside the block itself, not only on the insert.
A batch revision workflow has to search the text-bearing entity types themselves — model space, every paper space layout and every block definition — rather than only what is visible on the sheet in front of you.
How batch revision updates work
1. Upload the drawing set
Select the DWG files that belong to the revision package.
2. Define the revision rules
Enter one replacement or paste a whole list — for example REV A → REV B, ISSUED FOR REVIEW → ISSUED FOR CONSTRUCTION, 15 JUL 2026 → 27 AUG 2026. Rules can be prepared in a spreadsheet and pasted in as rows, or imported as CSV, when several values change at once.
3. Run the batch
The same rule set is applied across every selected drawing.
4. Review the audit report
Every replacement is recorded with the drawing, layout, layer and entity it happened in. Anything that could not be replaced safely is listed as skipped, with its reason — never silently guessed at.
5. Download the updated DWGs
Download the corrected set, in the same DWG version it arrived in, for final project review.
More than just Rev A to Rev B
A re-issue usually carries several changes at once, which is why a batch takes a rule list rather than one pair:
- Revision — Rev A to Rev B;
- Issue status — Issued for Review to Issued for Construction;
- Issue date — 15 July 2026 to 27 August 2026;
- Standard — EN XXXX:2021 to EN XXXX:2026;
- Project reference — PRJ-104-A to PRJ-104-B.
One batch can therefore be the complete administrative update that belongs to a new drawing issue.
Avoid changing the wrong text
A batch process is only useful if it is controlled. Rules carry their own case-sensitivity and whole-word settings, so REV A as a revision mark can be distinguished from the same letters appearing inside another string. Where several rules overlap, the order they are applied in is fixed and predictable rather than incidental.
The objective is not to replace as much text as possible. It is to make the intended changes and produce a record of exactly what happened.
Audit every revision change
Revision updates are usually part of a formal document-control process, so knowing what changed is nearly as important as changing it. Every batch returns a report you can read line by line:
- the drawing the change happened in;
- the original value;
- the replacement value;
- the entity, layout and layer it sat on;
- anything that was skipped;
- the reason it was skipped.
That gives the document controller or CAD team a concrete list to verify before the set is issued — and, when a drawing could not be processed at all, that file’s credit is refunded automatically.
Revision updates without opening AutoCAD
The person responsible for the issue is often a document controller, project manager, BIM coordinator, CAD manager or engineering administrator. They know exactly what has to change without needing to edit every DWG by hand, and the batch runs in the browser — so the repetitive text update stops competing for a CAD workstation.
When to use the title-block workflow instead
Revision text usually lives in the title block, but title-block updates involve more than revisions: company name, client name, project number, project address, drawing status, issue date, revision and approval information. If several of those fields change together, read updating title blocks across multiple AutoCAD drawings instead — it is the same engine, aimed at the wider job.
Find & replace for other drawing changes
The same batch workflow also covers:
- client-name changes;
- company rebranding;
- project-number changes;
- specification corrections;
- standard-reference updates;
- repeated spelling corrections;
- material-name updates.
The complete feature is batch find & replace text in multiple DWG files, and how to find & replace text in multiple AutoCAD drawings compares this against the other methods, including scripts and LISP routines.
FAQ
Frequently asked questions
How do I change Rev A to Rev B across multiple AutoCAD drawings?
Create a find-and-replace rule for the old and new revision values, apply it to the whole drawing set as one batch, and read the audit report before you issue the files.
Do I need to open every DWG individually?
No. The same replacement rules are applied across every drawing you upload, and the corrected set comes back together.
Can revision information inside title block attributes be updated?
Yes. Block attributes are covered on every insert, in every paper space layout and inside block definitions, which is where revision and issue-status fields normally live.
Can I update the revision number and the issue status at the same time?
Yes. A batch takes a list of rules, not a single pair, so the revision mark, the issue status, the issue date and a standard reference can all change in one run.
Can I paste revision changes from Excel?
Yes. Paste rows straight from a spreadsheet, or import a CSV. Each row is one rule — old value in one column, new value in the next.
Will measured dimensions change?
No. Only text is replaced. Measured dimension values and drawing geometry are never modified, and dimension text is touched only where someone has typed an override by hand.
How do I know which drawings were changed?
Every batch returns a line-by-line audit report — drawing, layout, layer, old value, new value — and anything that could not be replaced safely is listed as skipped with its reason.
Update the revision across the whole drawing set
Stop opening drawings one at a time to repeat the same administrative change. Define the rules once, apply them across the set, and read what changed.
