Sorry about the delay on this!
Ok without the assets I can only provide a VERY simple example of how you can create edge banding geometry using the Node Geometry Editor.

The white represents a cabinet panel and the black is the edge banding geometry.
These nodes create a single cabinet panel:
The nodes inside the blue frame create the edge banding:
In very simple terms, it starts by using the same box dimensions as the panel itself, then it sets the y-value of the positions of the vertices to be at the top of the panel’s bounding box in Y and then adds the panel thickness for the top vertices. Pretty simple and straight forward.
This is only for dynamically creating the geometry itself. Creating the material is an entirely different topic. I hope that’s a little bit helpful to you.
