Flattening out and dissolving faces using geometry nodes.
I have an object that will be 3D printed and I was wondering if geometry nodes can flatten out and dissolve faces. I currently select the faces and use S-X-0. The goal is to model this completely in geometry nodes to make it procedural with the ability to change various parameters like the heights and size.
See animation below of what I do now. Can Geometry Nodes do this?
My current node setup can extrude but not flatten and dissolve faces.
