I was looking for a way to "disconnect" all the vertices of a given selection from the rest of the geometry.

In other words, delete all the edges (edges only!) that include at least one vertex from the selection.

I posted a solution I found that works as I expected, but I wonder if there are more efficent ways to achieve this result.

  • $\begingroup$ I'm afraid there is a mistake in your question. The nodes you mentioned do exist in the latest version of Blender. Please consider rephrasing your question to ask, "How can I achieve this task?" instead of stating that the nodes do not exist. Thank you. $\endgroup$

  • $\begingroup$ Thank you for your response. In my question I said that I am afraid I am trying to do something too specific and that there might not be suitable nodes for it. I never meant to claim anything, I am just looking for help. $\endgroup$

  • $\begingroup$ @xWourFo The statement Delete all edges that contain at least one vertex would mean all edges would get deleted because an edge can only exist with exactly 2 vertices. You cannot have an edge with 1 vertex. So we are unsure what you mean by that? Consider rephrasing the title. And please also add more information on what you are trying to accomplish with screenshots perhaps. $\endgroup$

  • $\begingroup$ @HarryMcKenzie The statement in the title is "Delete all edges that contain at least one vertex from a given selection". I never edited it. $\endgroup$

  • $\begingroup$ @xWourFo Yes I know you never edited it but you have to edit it because the statement is incorrect since an edge always has exactly two vertices. Therefore, saying "at least one vertex" is redundant and misleading. $\endgroup$

I came up with this solution, it's probably not optimal but it seems to work fine. enter image description here

  • $\begingroup$ Sure. I am creating two instances of the Geometry. In the bottom one, all the vertices of the selection are deleted, so the edges are also deleted. In the top one, only the edges and faces are deleted. The result of the join is a Geometry where the edges are deleted correctly and the vertices are preserved, but there are also duplicate vertices, so that's why I used a Merge by Distance. $\endgroup$

    $\begingroup$ I think this setup will have the same output as if you removed all nodes but the bottom "Delete Geometry". $\endgroup$ Commented Jul 9 at 8:06
  • $\begingroup$ @MarkusvonBroady I think I did not made clear what I was trying to achieve, that's definetely my bad. I edited my question. $\endgroup$
