Just some heads up: I'm a beginner.
I was trying to outline some edges on my model with the wireframe modifier since I thought that was the easiest approach. I used a vertex group to tell the modifier where it can place itself but ran into a problem. Some edges caused the wireframe to connect to ghost vertices, but that seems to have fixed itself when I updated to the latest version of Blender (from 2.92.0 to 2.93.1). All is good in that regard.
But before I updated I did some debugging and found out something that bothered me.
When I updated to the latest version, I tried the same thing again (but with a cube) and it still persisted, as evident from the screenshot below (only the top front edge has been assigned to the vertex group).
So, what I'm asking is this: Is this normal?
As a beginner, this seems like it should not be happenning purely because of esthetic reasons. If someone wants to outline a singular edge on a model, only that edge should have the wireframe modifier applied to it instead of branching out to every vertex around it.
But then again, I'm not sure if this is the industry standard of outlining edges in Blender. Perhaps there is a better way of doing this I am not aware of and I'm just using the wrong tool for it.
