# How I can remove the right half of a geometry using a geometry node?

I have the following geometry, and I only need the left half

To remove the right part I'm trying to use the Mesh Boolean node with a bounding box scaled by half to do a difference between them, but I get his result

What I'm doing wrong? I would have expect from this node setup to cut the Mesh 1 in half

• I see you've got a solution, just a few thoughts on your initial setup: the left and right part are one object although the meshes are not connected, so there is one bounding box surrounding them both together. Scaling down on X by 50% will just make this box "thinner" in X direction towards its center, not just on one side, so the Mesh Boolean would cut out the middle of the object by half of its overall width. Even if the obejcts were separate and you had separate bounding boxes, scaling them on X would also just make them thinner towards there center and make them move towards each other.

• Now, I said this would usually make the Mesh Boolean cut out the center of the object - however, it does not even do that. But if you look closely, there is this small "speech bubble" with the letter i in it, indicating there is some information about a problem. Hover your mouse over it so it can tell you what is wrong with your setup and why it is not cutting out the center (which is not what you want , but what I would expect from this setup). I would guess the object you plug in there is an instance and not a mesh object, then the Mesh Boolean remains only showing the bounding box. Commented Feb 8 at 7:36
