Looking for experienced Archicad C++ API developer for lightweight model-data extractor add-on

briansia — Sun, 03 May 2026 04:10:34 GMT

Hi everyone,

I’m new here — hello to the Graphisoft / Archicad developer community.

I’m looking for an experienced Archicad add-on developer for a small paid task.

The v1 goal is a lightweight model-data extractor:

- read Archicad model/project data
- extract element IDs / GUIDs, names, classifications, layers/grouping info, dimensions, zones/room signals, and existing properties/metadata where available
- structure the data as JSON
- POST it to an HTTPS endpoint
- save a local JSON/log file if the POST fails

No writeback, no live sync, no complex UI for v1.

Later, Phase 2 may add bidirectional features such as writing IDs/status back into element properties, detecting changes, selecting/highlighting elements, or placing library elements.

I’m also trying to confirm whether the best route is the Archicad C++ API or whether Python API can support this kind of add-on properly.

If you have experience building Archicad add-ons and are interested, please reply or message me.

Thank you.

Operating system used: Mac Apple Silicon Tahoe

Hi Brian,

In case if you are still looking, I've developed a similar Add-On already for @Davor P here: https://audit.bim4bim.com/login/

Maybe it's a good idea also to talk to Davor if any collaboration would be possible for the two of you.

Also you can send me an email to bernd@archi-xt.com or just DM me here in the forums if you need more developers 🙂

Best,
Bernd
