📄 Flagship Tool

Merge PDFs by discipline. Automatically.

Turn a folder of AutoCAD or Revit sheet exports into named discipline sets — Architectural, Structural, Electrical, Mechanical, Plumbing, Fire Protection, Interior, and more — in one click. Sheet numbers are detected automatically, Revit PDF coordinates are corrected so Bluebeam Batch Sign & Seal works correctly on the merged set, and an optional grand combined set is produced alongside the discipline files.

✓ Automatic discipline sorting using AEC sheet numbering conventions

✓ Revit PDF coordinate correction for Bluebeam Batch Sign & Seal

✓ Page labels and bookmarks generated automatically from filenames

✓ Optional grand combined set created alongside discipline files

The Problem

Every permit submission requires the same painful process. You export individual sheets from Revit or AutoCAD, then manually sort them into Architectural, Structural, MEP discipline sets. With a 200-sheet drawing set this takes hours and introduces sorting errors. And if Bluebeam Batch Sign & Seal is in your workflow, Revit-exported PDFs can break the batch stamp placement across the entire set.

You've done this dance a dozen times. You know exactly how long it takes, and you know that somewhere in that manual sorting process, a sheet gets missed or put in the wrong discipline folder. Under deadline pressure, that's when mistakes happen.

PDF Merger eliminates this entirely. The tool reads the sheet number prefix automatically, understands AEC discipline conventions, and produces perfectly organized discipline sets in seconds. No manual sorting. No coordinate offset problems. Just discipline-named PDFs ready to submit.

How It Works

Export your sheets

Export sheets from Revit or AutoCAD as individual PDFs. No special naming convention changes required — PDF Merger reads the sheet numbers automatically from your existing export structure.

Drop the folder in

Point PDF Merger at your export folder. It identifies each sheet's discipline from the sheet number prefix and sorts them into groups automatically. A-series sheets become Architectural, S-series become Structural, E becomes Electrical, M becomes Mechanical, and so on.

Click "Start Merging"

Discipline-named PDF sets appear in your output folder, each correctly ordered by sheet number. An optional grand combined set is created at the same time. Coordinate origins are corrected automatically if you're using Revit exports.

Key Features

📊

Automatic Discipline Detection

Recognizes all standard AEC sheet numbering conventions — A, S, E, M, P, FP, I, C, L, and more. Discipline categories are created and populated automatically.

📐

Revit Coordinate Correction

Detects and corrects Revit PDF coordinates so Bluebeam Batch Sign & Seal places stamps correctly on the merged output. No need to sign dozens of sheets one by one.

🗂️

Grand Combined Set

Optionally create a combined set alongside discipline files — perfect for reference copies, archiving, or clients who want a complete bound set.

🔖

Page Labels & Bookmarks

Individual sheets within the merged sets get page labels and bookmarks derived from their original filenames automatically. No manual labeling required.

🔢

Smart Sheet Ordering

Sheets are ordered correctly within each discipline set, not alphabetically. E2.1 comes before E2.11, and discipline cover sheets appear first.

⚡

Mixed Exports

Handles folders containing both Revit and AutoCAD exports in the same operation. Sorts by discipline regardless of source.
