I'm a very beginner in Blender. I'm trying to connect two vertices laying on the same plane (these edges were a part of a face that I deleted earlier):

enter image description here

But when I select them and press J it shows the Could not connect vertices error. How to solve it? What I'm doing wrong?

    $\begingroup$ Hello :). To create new edges go Vertex > New face/edge/vertex (shortcut: F). J only works to connect vertices across an existing face. $\endgroup$ Mar 8, 2021 at 11:00

J only works on faces that already exist, it's basically a shortcut to cut a face between vertices (like the knife tool but just for cutting a face between vertices with a single button press) You want the F key for this one. It will "fill" an edge between the 2 vertices. If you want to make a face from 3 or more vertices, select the vertices and hit F to make a face.

F can be used in many different situations, like simply selecting a single edge that has other edges connected to it and boom, instant face. Try it out!

    $\begingroup$ I wouldn't say J is a shortcut for the Knife Tool. First of all it's the shortcut for Connect Vertex Path, which means you have to select vertices to use it. Second, the Knife Tool has its own shortcut K and is capable of cutting faces and edges everywhere without the need to select vertices (although cuts can be snapped to vertices). That's a very different tool. $\endgroup$ Mar 8, 2021 at 11:25
  • $\begingroup$ I didn't mean a keyboard shortcut, just an easier way to cut a face quickly between 2 verts, I'll update the answer $\endgroup$
