Add-on to automatically track/stamp elements with Teamwork user + date/time + create/reserve/edit

narcis — Tue, 06 Oct 2026 21:55:59 GMT

Hi all,

We work in Teamwork on BIMcloud (Archicad 28) with several users in the same project. As BIM Manager I need a reliable, automatic record of WHO did WHAT to each element and WHEN.

What I'm looking for:

1. Automatic stamping on the element itself
Every time an element is created, reserved or modified, a custom property (e.g. "EditedBy") should be filled automatically with:
- Teamwork user name (or initials)
- Date and time
- Action: Created / Reserved / Modified / Released
Ideally it keeps a short history (e.g. last 3–5 entries) and/or separate fields like "CreatedBy" and "LastEditedBy", so we can use them in schedules, labels and Graphic Overrides.

3. It must be automatic
No manual input from users and no scripts they need to remember to run – it should happen in the background on reserve, release or Send & Receive.

What I've already checked:
- Change Tracking (AC24+): useful for notifications, but the Tracked Changes list is cleared after receiving changes, only shows the latest change, and is per user. It's not a persistent history and isn't stored on the elements.
- Reservation info / Info Tag / colored workspaces: only show the CURRENT owner, not who created or previously edited an element.
- Expression properties can't read the Teamwork user name.
- Favorites with a preset "CreatedBy" value: works partly, but relies on users always placing from Favorites and doesn't capture later edits.
- Python / JSON API: as far as I can tell, it can't react to reservation events and has to be run manually by each user.
- Older thread asking for a similar "who did this?" feature (2020), with no solution at the time: https://community.graphisoft.com/t5/Project-data-BIM/History-of-element/td-p/221385

My questions:
1. Is there an existing add-on (free or commercial) that does this, or anything close?
2. Has anyone built something similar with the C++ API (e.g. catching element reservation-change notifications and writing the user name into a property or log file)? Any pitfalls with Teamwork, for example writing to elements just before release?
3. Is anything like this planned by Graphisoft, or should I post it on the Wishlist?

Any advice, existing tools or workflows would be much appreciated. Thanks!

I do not think any such item exists on the Roadmap, so if your don't get any answers that such an Add-On already exists, then posting a wish is the way to go.
