Shop Drawing Checker

Buildability review, before fabrication

Catch the detailing errors that stop a beam from being built.

Upload a shop drawing and get back an itemised buildability verdict — every fitting located, every dimension traced to a real dimension line, every gap named. No walkthroughs, no invented numbers.

What it does

Criterion-by-criterion review

Every sheet is checked against the detailing rubric — dimensioning, part location, hole patterns, weld and fit-up callouts — with a PASS, FLAG or FAIL and a plain reason.

Evidence, not guesswork

The model must build a dimension inventory from what is actually drawn. Recalled catalogue sizes and unattributable numbers are rejected as evidence.

Patterns across the job

Statistics rank the criteria your drawings fail most often, by rubric category and by member type, so detailing standards can be fixed at the source.

Invite-only with spend caps

Access is approved per person, each account carries its own review budget, and a global kill switch stops all spending instantly.

Connect your assistant

A built-in MCP server lets Claude, ChatGPT or Cursor read your projects, drawings, review verdicts and failure statistics — as you, under the same permissions.

Built for the checker

Zoom and pan inside the sheet, redline directly on the drawing, override any verdict with a note, and export a two-page PDF for the fabricator.

1. Upload

Drop in a single sheet or a multi-sheet PDF; pages are split and filed under a project and phase.

2. Review

Run the review, work through the failures on the drawing itself, and override anything the model got wrong.

3. Issue

Export a concise PDF for the fabricator and watch the failure statistics improve job over job.
