Native elements, both directions
Walls, windows, doors, slabs, roofs, beams and columns are pushed and pulled as real, editable objects in every application.
One 3d model.
cadwork 3d | Revit | Archicad
Finally, time for the real work. Native 3d model synchronization for architects and timber engineers.
Built for real round-trips, not one-way exports
Know before you pull
The pull preview shows whether every incoming element will be created, updated or remain unchanged.
Updates, not duplicates
Every element carries a stable identity across applications, so repeated pulls update in place.
Versioned with messages
Add a message to every push and see who changed what, when. Full model history is stored in the cloud.
Material mapping
Map building materials once in a shared table. Layer functions and thicknesses survive the round-trip.
Openings that stay put
Window and door orientation is transported geometrically and verified on import.
Three steps to a shared model

- 2
Push
Select elements, write a short message and push a new cloud model version.
- 3
Pull
Review the change preview, pull, and continue working on native elements in your tool.

Developed with the industry, tested in practice
Cadwork Connect grew out of research at ETH Zürich and is being tested on real projects by timber construction companies and architecture partners.
“Building up a cadwork model normally takes one to two weeks. With Cadwork Connect it happens in seconds, with no effort.”
“A completely new way of working together. With Cadwork Connect, only the data that really matters gets synchronized.”
Built on open source
Cadwork Connect builds on COMPAS, the open-source framework for computational research in architecture, engineering and construction. We contribute to the COMPAS package compas_cadwork.
compas_cadwork
COMPAS package for integrating with cadwork: create, manipulate and analyse 3D models directly in cadwork. MIT licence.

Common questions
Do I need all three applications?
No. Cadwork Connect links any two applications, or all three.
Is my model data safe?
Models are exchanged through a Speckle server: the public cloud or your own self-hosted instance.
What happens to elements I already pulled?
They update in place because every element keeps a stable identity across applications.
Which versions are supported?
Current cadwork 3d and Revit releases, plus Graphisoft Archicad 28.
