Edit Face works on the faces of a brush. It is how you select faces for materials and UVs, push and pull walls, extrude new geometry out of a face (a ledge, a pillar, a window frame), and tidy up faces that earlier cuts split into pieces.
Selecting faces
- Select a brush, pick Edit Face, and click a face. A click selects the whole face, even one that is split into pieces (by Subdivide, a cut, or an older CSG cut).
- Click a piece of the selected face again, or Alt+click any face, to select just the piece under the cursor.
- Double-click a face to select the whole connected region within the Linked angle (an arch's front, a curved strip). Keep the button held on the double-click and pull to drag the region at once.
- Shift+click adds, Ctrl+click toggles, Ctrl+Shift+click removes. Ctrl+A selects every face.
- Tools > Select by Material selects every face wearing the selected face's material.
The selected faces are what the Materials tab, the UV editor and Convert Face to Displacement act on.
Moving faces
Drag a face to move it across the horizontal plane; drag a selected face to move all selected faces. Use the gizmo to move along one axis.
Extruding
There are three ways to pull faces out into new geometry:
- Press F (Extrude Selected Faces): the selection follows the mouse along the faces' normal until you click. Esc drops it; hold Ctrl to snap it flush to a face. Alt+click a piece first to extrude that piece alone.
- Hold Alt as you start a drag: dragging a face pulls it out along its normal; dragging the gizmo pulls the selection out along its arrow or plane.
- The Extrude Selected Faces button pulls the selection out by Extrude distance along their average normal, bridged by new side faces. A negative distance pushes them in.
The buttons
| Button |
What it does
|
| Extrude Selected Faces |
Pull the selected faces out as one region by the extrude distance, bridged by new side faces.
|
| Inset Selected Faces |
Shrink each selected face inward by the inset amount, bridged by a ring of four-sided faces. Good for window frames and panels.
|
| Subdivide Selected Faces |
Split every edge of the selected faces into equal segments and divide the faces to match (quads into quads, triangles into triangles, other faces around a centre). Neighbouring faces take the new edge vertices, so nothing cracks; UVs and vertex paint are kept.
|
| Cut |
Cut the selected faces along a line you aim, like Loop Cut but through the selected faces alone: hover one of them to see the cut through the cursor (on the grid), Shift+wheel turns it 15 degrees, Ctrl+Shift+wheel 1 degree, click to cut. The pieces stay selected. Esc stops cutting.
|
| Weld Coplanar Faces |
Heal the selected brushes: fuse flat neighbouring faces of the same material back into single faces. Fixes walls split up by older CSG cuts. The shape is unchanged; displacement brushes are skipped.

| Linked angle (deg)

40

Double-click selects every connected face within this angle. Near 0 takes only the flat pieces a cut leaves behind; about 40 follows curved strips such as the underside of an arch or a cylinder's side.

| Inset amount

0.25

How far Inset shrinks each face's outline inward. Reduced per face where the outline would cross itself.
|
| Extrude distance
|
Metres
|
1.0
|
How far the Extrude button pulls the faces out. Negative pushes them in.
|
| Subdivide cuts
|
1 to 16
|
1
|
How many new vertices Subdivide puts along every edge. 1 splits a quad into 2 by 2, 2 into 3 by 3.
