Native macOS PDF workflow for AEC drawing sets

Navigate and mark up complex drawing sets.

Drawbridge turns large architectural PDFs into usable plan sets with automated bookmarks, page labels, referenced-sheet hyperlinks, simple vector markups, and fast native navigation on Apple Silicon Macs.

AEC workflow

From dense PDFs to a clean drawing index.

When a drawing set arrives unlabeled, out of order, or poorly bookmarked, Drawbridge helps recover structure fast: generate bookmarks and page labels, then hyperlink referenced sheet numbers so the set behaves like a coordinated drawing package.

1

Generate the index

Use the bookmark and page label generator to detect sheet numbers and create an accurate sidebar index for dense drawing sets.

2

Link referenced sheets

Run hyperlinking across the set so references like A-201 or S-103 become clickable jumps to the right sheet.

3

Move without losing context

After following a hyperlink, hold Option and press ← to return to the previous page.

Bookmarks + page labels

Create an accurate index from dense drawing sets.

Use the bookmark and page label generator when a combined PDF has weak navigation, inconsistent page names, or no useful index. Drawbridge reads the sheets, creates clean bookmarks, and applies page labels so the sidebar matches the actual drawing set.

The result is a reliable drawing index that makes review, markup, and coordination faster before anyone starts chasing sheets manually.

Sheet hyperlinks

Jump through referenced sheet numbers like a linked drawing set.

The hyperlink function finds referenced sheet numbers throughout large PDFs and links them to their matching pages. Instead of hunting through hundreds of pages, users can click a sheet reference and jump directly to the destination.

When you need to go back, hold Option and press ← on the Mac keyboard to return to the previous page, making large PDF sets much easier to navigate.

Mark up fast with editable vector tools

Add editable vector markups with pen, rectangle, ellipse, line, arrow, polygon, polyline, and text tools.

Native macOS app

Built for Apple Silicon Macs with native rendering and a focused desktop workflow.

Invert color mode

Review dense CAD drawings comfortably in low-light environments without losing drawing precision.

Interactive markups list

Track annotations across complex plan sets and jump directly to markup locations during review.

Why Drawbridge?

A bridge between drawings and decisions.

The name Drawbridge comes from the idea of bridging the gaps between architects, engineers, contractors, and the drawings they all work from. Drawbridge helps turn dense PDF sets into shared, navigable context: sheets are easier to find, references are easier to follow, and simple markups can carry review notes without leaving the drawing set.
