A2Z CIVIL ENGINEERS CNOTES ADD-IN
FREE AUTOCAD & CIVIL 3D ADD-IN • 2020-2027

Stop renumbering bubbles by hand.

Place keynote bubbles, build your construction notes table, and renumber the whole drawing in seconds. Built by civil engineers who got tired of doing it the slow way.

No cost · No ads · No catch

You have 40 keynote bubbles across six sheets. The client adds one note in the middle of the list.

Now every bubble after it is wrong.

You zoom in. Double-click. Retype. Thirty more times. You miss two, and QC catches them a week later.

What it does

  • 1

    Manage your notes in one place

    Create note categories, add notes, reorder them. Import from CSV, tab-delimited text, or other *.cnm files you already have. Everything lives in the drawing.
  • 2

    Place bubbles with one click

    Pick a note, click on the drawing. The bubble lands with the right number and the right shape — circle, hexagon, diamond, pentagon, star; eleven styles in all. Need a leader? Place the bubble with a multileader pointing straight at the object.
  • 3

    Renumber in seconds, not hours

    Bubble 3 becomes 4? Type it once and apply it to every bubble in the drawing — model space and every layout. Queue up several changes, reorder them, undo if you get it wrong.
  • 4

    Build the notes table automatically

    Insert a construction notes table for every category or just one. Update it later and it stays in step with the bubbles you actually placed.

How to get it

  • Step 1

    Download and install

    Close AutoCAD/Civil3D first. The installer does not need administrator rights.

    Since this is a recent public release, Windows may show a “Windows protected your PC” screen. Click More info → Run anyway. For transparency, you can review the installer’s VirusTotal scan report before you install. If your antivirus blocks or quarantines the file, please don’t disable it. Just email us at contact@a2zce.com and we’ll help.

    Frequently Asked Questions

    • 1. Is it really free?

      Yes. No cost, no trial period, no upsell inside the tool.

    • 2. Why do you need my Request Code?

      Each licence works on one computer, and the Request Code tells us which one. It’s a one-way hash — it can’t be reversed, and it reveals nothing about you, your files, or your machine.

    • 3. Why can't I register with Gmail?

      We issue this tool to working civil engineers and surveyors. A company email address is how we confirm that.

    • 4. What if I change computers?

      Register again with the new Request Code and we’ll issue a new Activation Code.

    • 5. What happens after two years?

      Register again for a free renewal.

    • 6. Do I need an internet connection to use it?

      No. Activation is offline. Once activated, the tool never phones home.

    • 7. Can I share my Activation Code with a colleague?

      It won’t work — each code is tied to one computer. Ask them to register. It’s free.

    • 8. Is the installer safe?

      Yes. The installer only copies the add-in into your Autodesk plug-ins folder. It doesn’t need admin rights, doesn’t install services or startup items, and the add-in never connects to the internet. Because the tool is new and not yet widely downloaded, a few antivirus engines may flag it using generic machine-learning rules. You can review the full VirusTotal scan report yourself.
