F2
Introductionโ
The F2 addon extends the default F fill key so a single edge or vertex can start a run of faces. You keep pressing F and the fill advances one face at a time, which speeds up repetitive poly-modeling far more than the stock fill behavior.
Key Takeawaysโ
Repetitive Filling
Select one edge on the boundary and press F repeatedly to fill the whole run of faces.
Single Vertex Input
Start from one selected vertex. Each press of F adds a face and the next vertex.
Directional Sensitivity
Hover the cursor to the left or right of the selection to set which side the new face fills onto.
Installationโ
The F2 add-on is included with recent Blender versions and only requires activation.
Step-by-step installation:
- Navigate to the Edit menu and select Preferences.
- In the Preferences window, select the Add-ons tab.
- Use the search field to find "F2".
- Enable the add-on by checking the box next to "Mesh: F2".
Usageโ
Use the F2 add-on primarily in Edit Mode for filling gaps in mesh geometry.
Edge-Based Repetitive Fillingยท edges
Enter Edit Mode (Tab), switch to Edge Select (2), select a single edge adjacent to the area to fill, then press F repeatedly to fill faces along the boundary.
Single Vertex Fillingยท vertices
Enter Edit Mode, switch to Vertex Select (1), select a single vertex adjacent to the open area, then press F repeatedly. Each press creates a face and a new vertex aligned with the surrounding geometry.
Control Fill Directionยท mouse
Select the edge/vertex input, hover the mouse over the side (left or right) where the new face should go, then press F to create it in that direction.
In an Investigationโ
- Repetitive geometry: build runs of identical faces (brick courses, fence slats, rowing of windows) faster than manual fills allow.
- Quick patches: close small open areas in a reconstructed mesh with a consistent fill direction.
- Topology groundwork: lay down clean, even edge runs that later tools (bevel, subsurf, retopology) can build on.
Limitationsโ
- Operates in Edit Mode only.
- Works best on open boundaries. Closed or manifold selections do not produce new faces.
