I try to find a way to create a window frame like object procedurally with Geometry Nodes. The base object is a grid-mesh (we can assume, it is 2D, rectangular quad mesh, where every lines are orthogonal, but the spacing between individual lines can vary). There is an instance mesh, that I'd like to distribute across H and V edge loops. But I don't know, how can I find the edge loops in geom nodes, in the same way as with the ALT + click in edit mode on a line.
Here is an illustration, what I want to achieve:
A better example, where two separate objects are used as H and V lines:
