Union of geometries

Hi everyone,

I am struggling to make a union out of these geometries. When using the Solid Union, I am unable to connect more than 1 geometry (even when pressing shift button). Any reason why this could happen?

Use Merge
2021-07-15 13_17_23-Window
and if Merge output is becoming a tree, flatten its inputs or its output.

Thanks a lot Riccardo! That worked easy and perfectly :slight_smile:
