Connect vertices
Connect vertices across an existing face. The new edge divides that face without moving its vertices.
Before you start
Use Vertex Select in mesh edit mode. Choose suitable vertices across an existing face. Connect divides the existing surface; it is different from filling an open boundary or merging vertices into one.
Use the operation
Add an edge between existing face vertices.
- Select two non-adjacent vertices on a simple face for the first connection.
- Choose Connect Vertices from the vertex context menu, or press J with the viewport focused.
- Inspect the new edge and the faces on either side.
- Continue with another deliberate connection if the surface needs further division.
Controls and choices
| Controls | What changes |
|---|---|
| Chosen vertices | Must provide a valid connection through the existing topology. Selecting unrelated vertices is not a request to bridge separate objects. |
| Existing edges | Already connected or adjacent vertices may not create a useful new division. |

Before
Two selected corners
After
A connecting edge
Check the result
The vertex positions should stay in place while a new edge divides the face. If Connect is unavailable, simplify the selection and inspect whether the vertices share a suitable surface. Use Knife when the required endpoints do not yet exist.
