Trinh Tools exists because the right tool didn't — so it was written.
I'm a practicing MEP engineer. Every project I've worked on has run through the same PDF gauntlet: export from Revit, try to merge by discipline, wonder why Bluebeam Batch Seal is stamping in the wrong location, manually sort permit sets by building the night before a deadline, and try to figure out which revision of sheet E2.11 is actually the current one.
These aren't exotic problems. They come up on almost every project, for almost every engineer working in Revit and Bluebeam. And the solutions that existed were either too expensive, too fragile, or required someone with Dynamo scripting experience to set up.
So I wrote the tools myself. PDF Merger came first — because discipline sorting was eating hours on every permit submission. Fix PDF Coordinates followed when I finally traced a recurring Bluebeam stamping issue back to how Revit writes its PDF coordinate origin. The rest of the suite grew from there, one frustration at a time.
I use every one of these tools on real projects. They've been tested on actual permit submissions, addenda packages, and coordination sets — not just on sample files. When something breaks or doesn't handle a naming convention correctly, I hear about it because it happens to me first.
Trinh Tools is not a software company. It's one engineer's answer to workflow problems that shouldn't exist — built carefully, distributed at a price that makes sense for individual practitioners and small AEC firms, and sold with a simple promise: pay once, own it forever.
Each tool does exactly one thing and does it well. No feature bloat, no unnecessary settings, no learning curve. If you can describe the problem in a sentence, the tool should solve it in a click.
Your PDF files, project names, folder structures, and drawing sets are private. They never leave your computer. No cloud upload, no telemetry, no analytics running in the background. The tools process everything locally.
One-time payment, lifetime license, all future updates included. No subscription to manage, no renewal to forget, no price that doubles in year two. The price is on the page.
Strict IT policies, managed workstations, no admin rights, offline job sites — these are real constraints in AEC environments. The tools are designed around them, not against them.
Every tool has been used on actual permit submissions, coordination sets, and deadline-driven deliverables. Not just verified to run — verified to be useful when the pressure is on.
When something doesn't work, I want to know. Email support goes to the person who wrote the tool. If a naming convention isn't supported, I can often add it in the next update. There's no support tier — everyone gets a real answer.
The tools in Trinh Tools weren't designed as a product. They were written as solutions, one at a time, whenever a workflow step was eating too many hours. They happen to solve the same cluster of problems that come up when you're managing PDF deliverables in a Revit + Bluebeam shop.
All six are included in every license. A single launcher app lets you access them all from one place, with only the tools you've installed appearing in the list.
Start Free Trial →A single dashboard that shows only the tools you've installed, lets you reorder them, and tracks which ones are currently running. Clean, no bloat.
