How do you join edges in edit mode in Blender?

To join edges in Edit Mode in Blender, you typically select the edges you want to connect or form a face from and press the F key. This action attempts to create new geometry, such as an edge or a face, based on your selection.

Here’s a simple breakdown:

1. Enter Edit Mode: Make sure your object is selected and you are in Edit Mode (press Tab).
2. Switch to Edge Select Mode: Press 2 on your keyboard to switch to Edge Select mode. As mentioned in the reference, pressing 2 allows you to easily select edges.
3. Select the Edges: Select the edges you want to join. You can select multiple edges by holding Shift while clicking.
4. Join Edges: With the edges selected, press F.

What Happens When You Press F?

The F key in Edit Mode is versatile and context-aware:

• Creating a Face: If you select a loop of edges that form a closed boundary (like the four edges of a square), pressing F will create a face filling that boundary. This is similar to selecting the vertices defining those edges and pressing F to make a plane, as indicated in the reference.
• Creating an Edge: If you select two non-connected vertices, pressing F will create an edge between them. (While the question is about edges, this shows the F key's general function).
• Filling Holes/Creating Faces: If you select edges forming the boundary of a hole in your mesh, pressing F can often fill that hole by creating a new face.

Quick Reference Table

Key/Mode	Action	Purpose in Joining Edges Context
Tab	Switch between Object Mode and Edit Mode	Necessary to access mesh components like edges.
2	Activate Edge Select Mode	Allows direct selection of edges. (As per reference)
Shift + Click	Add to selection	Select multiple edges at once.
F	Fill/Join	Creates new geometry (face or edge) from selection. (As per reference for joining vertices to make a plain/face)

Practical Tips

• Ensure the edges you select form a valid shape for F to create a face. An edge loop is a common scenario.
• If F doesn't produce the desired result (e.g., creates an unwanted face or nothing happens), your selection might not be suitable for this operation. You might need to select vertices instead or use different tools like "Bridge Edge Loops" (often found in the Edge menu, Ctrl+E).
• Remember that the F key connects existing selected elements. It doesn't merge edges in the sense of reducing edge count along a straight line, which is usually done by dissolving (e.g., X > Dissolve Edges).

In summary, selecting edges using 2 and pressing F is the primary method in Blender's Edit Mode for "joining" edges to create new faces.
