K

The Knife tool lets you interactively «cut through» faces, subdividing them and creating a chain of new edges along the way.

Uso

First, select the tool in the Toolbar or press K. The cursor will change into a scalpel to indicate it’s active.

Click LMB at the place where you want to start cutting. This can be anywhere: on an existing vertex, edge or face, or even outside of the mesh.

Move your mouse to the next location. You’ll see a purple line indicating the new edges that will be created, and green squares indicating the new vertices. Click LMB to confirm: the green squares will turn red, and you can define the next line in the cutting path.

Once you’re done, press Spacebar or Return to apply the cuts. Alternatively, press Esc to cancel.

Consejo

By using Edición de varios objetos a la vez, you can cut multiple objects at the same time.

Opciones de herramientas

These settings are only available when using the tool from the Toolbar (not when pressing K). They can be found in the Tool tab of the Propiedades editor and of the Sidebar.

Ocluir geometría

Only cut geometry visible on screen. By disabling this, you can cut all the way through the mesh, including faces that are on the backside or behind others.

Sólo seleccionados

Only cut through selected geometry. You can press Shift-K instead of K to start cutting with this option enabled.

Rayos X

Show the cutting path even if it’s occluded by geometry.

Medición

The measurements to show along the cutting path: distances, angles, or both.

Sólo distancias.

Sólo ángulos.

Tanto distancias como ángulos.

Adherencia a ángulos

Whether to constrain the cutting lines to multiples of the Snap Increment angle.

Ninguno:

Sin adherencia.

Pantalla:

Snap in screen space (the viewing plane).

Relativo:

Snap in a plane on the geometry, relative to an adjacent edge or cutting line.

Relative snapping at 90°. Blender hilights the reference edge in yellow and shows the snapping direction in white.

Controles

These keyboard shortcuts are shown in the status bar while cutting. They’re available both when using the tool from the Toolbar and when pressing K.

Cortar LMB

You can either click to add a new cutting line, or drag to create cutting lines as you move the mouse over edges.

Cerrar bucle - doble clic LMB

Adds a cutting point at the cursor (just like when single-clicking) and then connects it to the first point in the current path, closing the loop.

Detener RMB

Completes the current cutting path and begins a new one. The cursor will snap to previously defined cuts.

After defining the horizontal cut, press RMB and define the vertical one.

Result after applying.

Confirmar Espacio or Intro

Confirms the cut, turning the cutting paths into edges.

Cancelar Esc

Cancela el corte.

Deshacer Ctrl-Z

Undoes the previous cutting line (or, if you dragged the mouse before, all the cutting lines created during that drag).

Adherir a punto medio Mayús

Hold to snap the cursor to the center of edges.

Ignorar adherencia Ctrl

Hold to temporarily stop the cursor from snapping to existing vertices, edges, and cutting lines.

Cortar a través: C

Also cut through occluded faces, instead of only the visible ones. This is linked to (and the opposite of) the Occlude Geometry setting above.

Restringir eje X, Y o Z

Constrains the current cutting line to a global axis. Press a second time to use the object’s local axis, and a third time to disable the constraint again.

Medir S

Cycles between measurements to show: distances, angles, or both.

Rayos X V

Toggles whether to display cuts occluded by geometry.

Restringir ángulo A

Constrains cutting lines to multiples of the Snap Increment angle. This angle can be specified in the Tool Settings before cutting (see above) or typed while cutting with Angle Constraint active.

By default, the snapping is done in the Screen plane. Press A a second time to snap in planes on the geometry, Relative to an automatically chosen edge or cutting line. You can press R to select a different reference line.

Press A a third time to disable the snapping again.

Limitaciones conocidas

Vértices duplicados

If a cut creates duplicate vertices, this is often caused by the clipping range being too large. Try increasing the Clip Start to avoid this problem. Also see Depth Troubleshooting for details.
