Hi @Manuel_Emmenegger ,
You’ve stumbled across a bit of a nasty gap in our transition from v2 (legacy) connectors to our next gen (v3) connectors.
The IFC file import logic now produces v3 data, which is only consumable in our v3 connectors. (see our announcement of this new IFC importer)
We are close to having our first alpha release of the next gen grasshopper connector, which should be able to receive the current IFC import data without missing elements.
We should have our first alpha release out sometime soon. So, you’ll have to wait for this unfortunately
