From export to submission in minutes.

1

Export from Revit or AutoCAD

Export your sheets as individual PDFs the way you always have. No special settings, no naming conventions to change.

Point the tool at your export folder. Sheet numbers are detected automatically from filenames using AEC naming conventions.

3

Click once. Get your output.

Your merged sets, fixed coordinates, or split permit packages are waiting in the output folder. Ready for Bluebeam or direct submission.

Built on the same projects you work on.

Trinh Tools wasn't designed in a product meeting. It was written by a practicing MEP engineer who got tired of spending hours sorting PDFs, chasing coordinate errors, and building permit packages by hand the night before a deadline.

Every tool solves exactly one problem, does it reliably, and gets out of your way. No bloat. No learning curve. No cloud dependency. No subscription to justify at budget review.

Your files never leave your computer. Your projects stay private. The tools work offline. And you pay once.

🏢

Built for AEC workflows

Understands discipline codes, sheet numbering, revision history, and permit packaging — because it was designed inside a firm that does this daily.

🔒

Privacy first

Your PDFs and project data never leave your machine. No telemetry, no analytics, no cloud upload. The tools work completely offline after activation.
