Extrude a vertex
Extend a selected vertex and connect it to the new vertex with an edge. This wire edit creates an edge rather than a face.
Before you start
Enter mesh edit mode and use Vertex Select. Select a vertex at the end of a wire or at the intended start of an extension. A vertex extrusion creates connected edges; it does not by itself make a filled surface.
Use the operation
Extend a wire path one segment at a time.
- Select the endpoint and choose Extrude in the vertex context menu.
- Move the newly created vertex away from the source to define the next segment.
- Confirm, then repeat from the new endpoint when another segment is needed.
- Inspect the path from another view before filling or connecting it to other geometry.
Controls and choices
| Controls | What changes |
|---|---|
| Vertex selection | Each selected vertex can contribute to the extension. Select one endpoint for a single new wire segment. |
| Offset | Determines the new edge's length and direction. A zero-length segment is not a useful extension. |

Before
A selected wire vertex
After
A new connected vertex
Check the result
Confirm a new edge connects the original and new vertex. Multiple selected endpoints can create more geometry than expected. An open wire has no surface to shade; use a suitable closed boundary and Fill when you need a face.
