Threw together this little experiment last week. Its a kinda proof of concept of constructive solid geometry in SketchUp
You can download it here

You will get access to the window through: Extensions > Open Constructive
Clicking on the nodes in the graph will allow you to edit their parameters.
Clicking on the “apply” button will add a group to your model (currently very small and at the origin)
Modifying the node graph itself is currently not enabled
It is just an experiment! But interested in initial feedback
