Use case · Drawing review
P&IDs, isometrics and layouts checked object by object against the standards and specifications that govern them, with what changed between revisions surfaced on its own.
The problem
Checking an isometric means holding a weld class, a line number, a material callout and a dimension in mind at once, and knowing which clause governs each. It is slow, it does not scale, and the discipline reviewers who do it well are the ones with the least time.
Then the drawing is reissued. Nothing tells you what moved, so the safe answer is to start again.
A drawing can revise a dozen times between first issue and as-built. Most of each revision is identical to the last.
Reviewing it as a new document means paying full price for a change that touched a handful of objects.
What gets checked
Welds, valves, fittings, line numbers, materials and dimensions are each checked against the clause that governs them. A finding lands on the object it belongs to, so a reviewer knows where to look on the sheet.
Illustrative. Each finding names the clause it failed and the place on the sheet it came from.
Across revisions
Most of a revision is identical to the one before it. standrdX establishes which objects moved and puts the reviewer straight onto them, rather than back at the top of the sheet.
A finding cleared at one revision can quietly reappear at the next. Comparing revisions is how you catch that without reading everything again.

ILLUSTRATIVE COMPARISON
Where it fits
Drawings ingest as project documents alongside the specifications and standards that govern them, so a run covers the drawing set and the datasheets together and the findings land in one register.

Same project, same standards, same findings register.
FAQ
AI drawing review is the check that what is drawn meets the requirements that govern it. An AI drawing checker reads the sheet as engineering content rather than as an image. standrdX reads P&IDs, isometrics and layouts as engineering objects rather than pages, checks each against the applicable clause, and raises findings against the object they belong to.
P&IDs, isometrics, weld maps, general arrangements and layout drawings, supplied as PDFs. Drawings sit in the same project as the standards and specifications that govern them.
The two issues open beside each other with the differences highlighted, and a list names each one in plain language with a severity against it. What did not move is carried forward, so the reviewer only works the delta.
That is one of the reasons to compare revisions rather than re-read. A discrepancy that reappears at a later issue is surfaced rather than assumed closed.
Source quality changes what can be read reliably, and a poor scan is a poor scan. Put a few of the worst sheets you have through an evaluation early; that answer is specific to your archive, not something to take on a promise.
The discipline that owns the drawing. Findings are routed rather than pooled, and nothing closes without an engineer ruling on it.
Next step
Run standrdX across both and see what it says changed, then check that against what your reviewers found the first time.
