How to implement this editing in geometry nodes?
I tried to implement this change at the geometry nodes.
My approach was to create a vertex group for these edges and then add a geometry node across the entire plane. Within the geometry node, I separated the edge using a Separate Geomtry node (Selection: Vertex Group), converted it to a curve, and then used a Resample Curve Node to evenly segment it.
However, the final problem, as clearly shown in the video, is that the vertices of the two edges cannot be merged.
So I'm wondering if I shouldn't have separated that edge, or if there's a better solution?
Thank you for any help.
