PDF tools that quickly prepare
construction drawings for submission.

Six purpose-built tools for AEC firms that prepare construction drawings over and over. Built by a practicing MEP engineer to speed up drawing preparation, reduce quality-control issues, and automate the sorting, sealing fixes, and manual PDF steps that slow down real projects.

Merge by discipline, fix Bluebeam Batch Sign & Seal placement on Revit-exported PDFs, split by building, rename sheets, and assemble latest full sets without rebuilding the workflow every time.

Six tools. One license. Built for repeated drawing delivery.

All six tools are included with every license so your team can prepare, check, split, rename, and assemble drawing sets without patchwork workflows.

📄

PDF Merger

Merge drawing sets by discipline automatically so Mechanical, Electrical, Plumbing, and Fire Protection deliverables are prepared in the right order. Also corrects Revit PDF coordinates so Bluebeam Batch Sign & Seal places stamps correctly across the merged set.

Fix PDF Coordinates

The essential fix when Revit-exported PDFs break Bluebeam Batch Sign & Seal placement. Individual signing is fine, but batch signing dozens of sheets at once fails until the PDF coordinates are corrected.

🗂️

General PDF Merger

An all-purpose merger for teams handling lots of PDFs. Combine and rename files quickly while also generating page labels and bookmarks from your filenames in one click.

🗃️

Latest Full Set Builder

Scan a project directory, find the newest version of every sheet, and build a Latest Full Set folder without waiting for Revit to load. Outputs both individual sheets and merged discipline sets.

🏗️

PDF Split Per Building

Split sets by building for AHJ submissions using your sheet index. Automatically creates building-specific folders and pulls the correct drawings from a master folder to reduce tedious, error-prone manual sorting.

🏷️

Rename to Sheet Number

Quickly rename individual sheet PDFs to just the sheet number by identifying the sheet code from the filename. Ideal when the deliverable requires clean, sheet-number-only PDFs.

From export to submission in a few clicks.

1

Export from Revit and/or AutoCAD

Export your sheets as PDFs the way you already do. Start from the same drawing output your team uses today.

2

Process your PDFs for the deliverable

Use the PDF Merger, General PDF Merger, PDF Split Per Building, or the tool that fits the submission requirements for that project.

3

Prepare construction drawings for submission

Within a few clicks, you have sorted, merged, checked, split, or renamed PDFs ready for issue, review, signing, sealing, or direct submission.

Built around the work of preparing drawing sets correctly.

Trinh Tools was written by a practicing MEP engineer and project manager who needed deliverables prepared faster, in the right order, and with fewer quality-control misses. The goal was to automate sorting, merging, checking, and coordinate fixes that otherwise stay manual for far too long.

These are not exotic problems. They are recurring submission tasks that show up across real projects, re-issues, and permit packages. Each tool was built to remove one repeatable source of wasted time or avoidable error.

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, building splits, and permit packaging because it was designed around repeated construction drawing submissions.

🔒

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.
