The problem

Checking drawings is the part nobody has time for.

Hours lost to manual checking

Senior drafters spend whole afternoons redlining sheets by eye, on work that never appears on an invoice.

Errors that slip through

A missed tag or an unapplied markup becomes a revision, a delay, and an awkward conversation.

No audit trail of what was checked

When a query lands six months later, nobody can show what was reviewed, by whom, or against which rules.

Four modules

One review pass, four ways of looking at the drawing.

Standards Checker

Check drawings against client-specific rules, layer conventions and title block requirements.

Automated QA

25+ quality checks covering scales, dimensions, annotation, references and sheet setup.

Revision Comparison

Diff two versions of a drawing and see precisely what changed between issues.

Revision Checker

Upload the previous and current revision and see every change between issues.

Redline Verifier

No other tool does this

Upload the marked-up drawing alongside your revised sheet. VerifyCAD reads every redline and confirms, markup by markup, whether the change was actually made — so nothing gets signed off as complete when it isn't.

Each markup matched to the revised drawing
Applied, partially applied or missed — stated plainly
Works across a full drawing set, not one sheet at a time
Every decision recorded in the issued report

The Redline Verifier

Coming soon

See exactly what was missed.

When a client marks up a drawing, someone has to check every change was actually made. VerifyCAD does it automatically — comparing the markup against your revised drawing and flagging anything that was missed.

The marked-up drawing

The client's markup — every change they've requested, circled, clouded and noted.

Your revised drawing

Your reissued drawing — the changes you've made in response to the markup.

What was missed

VerifyCAD's result — every markup matched to your revision, with anything missed flagged clearly.

No more checking redlines by eye. Every markup verified, every miss caught — in minutes, not hours.

The Revision Checker

Coming soon

See exactly what changed between revisions.

Upload two versions of a drawing and VerifyCAD highlights every difference — what was added, removed, or moved — so nothing slips through between issues.

Previous revision

Your earlier revision — the starting point.

Current revision

Your new revision — with changes made.

Changes detected

VerifyCAD's result — every change identified and classified.

Stop comparing drawings side by side. VerifyCAD finds every change between revisions — in minutes, not hours.

Who builds it

Built by people who draw for a living.

VerifyCAD is built and used every day by Outsource CAD, a UK CAD drafting agency. Every drawing they deliver is run through it. This isn't software built by a startup that's never drawn a P&ID — it's built by a working drafting team.
