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.
All six tools are included with every license so your team can prepare, check, split, rename, and assemble drawing sets without patchwork workflows.
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.
Learn More →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.
Learn More →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.
Learn More →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.
Learn More →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.
Learn More →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.
Learn More →Export your sheets as PDFs the way you already do. Start from the same drawing output your team uses today.
Use the PDF Merger, General PDF Merger, PDF Split Per Building, or the tool that fits the submission requirements for that project.
Within a few clicks, you have sorted, merged, checked, split, or renamed PDFs ready for issue, review, signing, sealing, or direct submission.
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.
Understands discipline codes, sheet numbering, revision history, building splits, and permit packaging because it was designed around repeated construction drawing submissions.
Your PDFs and project data never leave your machine. No telemetry, no analytics, no cloud upload. The tools work completely offline after activation.
Buy once and use it indefinitely. No annual renewals, no subscription management, no license expiration. All future updates included.
Portable install. No admin rights. Nothing written to the registry. Works in environments with strict IT policies — just whitelist the folder.
AEC firms already pay enough annual software fees. Join the waitlist now, then be first to try it on a real project once launch and licensing are ready.
