Trinh Tools exists because recurring PDF submission work was taking too long, creating avoidable quality-control issues, and pulling engineers into repetitive cleanup work.
I'm a practicing MEP engineer and project manager. On real projects, our deliverables are construction drawings that have to be prepared correctly, in the right order, with the right sheets included, and often packaged differently depending on the client or AHJ submission requirements.
That means the same PDF work keeps showing up: merging sets by discipline, checking sheet counts, fixing weird sheet numbering, splitting by building, renaming files cleanly, and dealing with Revit-exported PDFs that break Bluebeam Batch Sign & Seal placement. These are not exotic problems. They are recurring jobs that quietly eat hours and introduce mistakes when handled manually.
The available solutions were often too expensive, too fragile, or too dependent on one-off internal automation to be practical. So I started building the tools myself. PDF Merger came first to speed up discipline-based issue sets. Fix PDF Coordinates followed after tracing a recurring Bluebeam Batch Sign & Seal problem back to Revit's PDF coordinate origin. Then came the supporting tools for general merging, building splits, sheet-number renaming, and assembling the latest full set from revision-heavy projects.
These tools were built to improve the speed of preparing drawings and reduce quality-control issues by automating sorting and removing manual steps. They have been tested across hundreds of real-life project situations: permit submissions, addenda, deltas, discipline issue sets, and re-issued drawing packages where a small PDF mistake can create a big delay.
Trinh Tools started as one engineer's answer to workflow problems that should not take this much effort. It has grown into a software company focused on carefully built tools for MEP firms and AEC teams that need reliable PDF workflows without bloated pricing, fragile scripts, or subscription-heavy overhead.
Each tool is focused on a real submission task: merge, sort, split, rename, quality-check, or fix coordinates. No feature bloat, no unnecessary setup, and no need to rebuild the workflow from scratch every time.
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. Building this in-house takes dozens of hours and ongoing maintenance. Trinh Tools is priced to save firms that development cost without locking them into a subscription.
Strict IT policies, managed workstations, no admin rights, offline job sites, and repeated deliverable deadlines are real AEC constraints. 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, but tested on hundreds of real-life project situations where speed and accuracy both matter.
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 were written one at a time to solve repeated drawing-preparation problems: discipline merging, Bluebeam Batch Sign & Seal issues on Revit-exported PDFs, page labels and bookmarks, building splits for AHJ review, sheet-number cleanup, and finding the latest version of every sheet without waiting on Revit.
All six are included in every license. Together they handle the repetitive PDF work that happens after drawings are exported and before the submission is ready to send.
