All the “topo points” are components made up of two edges. They should intersect (to form four edges) but currently somehow don’t.
But their “intersection” is at the component’s local origin. You need to find a way to get a real guidepoint at the local origin and then get rid of these two (four) edges.
There are plugins that can handle pointclouds from guidepoints to create a (curved) surface out of them.
