How it works

1

Download the tool set

Enter an email and the .btx downloads — every symbol in the set, drawn as clean vectors.

2

Import into Bluebeam

Tool Chest → Manage Tool Sets → Import. The set appears as its own tab, ready to drop onto any sheet.

3

Or skip the import

Open a symbol in Notch and it's already a tool — live vectors that size to the sheet's scale, on any device, no install.

Frequently asked questions

How do I import the heating tool set into Bluebeam Revu?
Download the .btx file, open Bluebeam Revu, go to Tool Chest → Manage Tool Sets (the gear icon) → Import, and pick the file. The set appears in your Tool Chest ready to drop onto any PDF.
Are these free for commercial use?
Yes. Every set is free to download and use on any project, commercial included. Enter an email and the file is yours — we send occasional Notch updates, unsubscribe anytime.
How are these different from the symbols in Notch?
Every symbol here is a built-in tool in Notch, drawn as live vectors rather than a pasted image — recolour it, resize it, rotate it, and it drops at true size on a calibrated sheet. Click Open in Notch on any symbol to try it on a real drawing, no account needed.

Leave the desktop behind. Keep the capability.
