Knife Help

Shortcut: {{knife tool}}

Quick Shortcut: {{knife quick}}

The Knife tool allows you to cut into the existing geometry similarly to Blender's Knife tool.

Note: the Knife tool will only cut into existing geometry; it will not create new vertices, edges, or faces.

If nothing is selected, the first insert will

  • insert a new detached vertex if the mouse is hovering a face,
  • split the hovered edge,
  • select the hovered vertex, or
  • set a knife starting point (does not create a new vertex).

The subsequent insertions will cut in new edges, splitting faces and edges accordingly.

Note: an existing face will not be split until there are distinct entrance and exit vertices. Until the face can split, the created vertices and edges will be non-manifold (possibly detached) geometry.

Creating

{{insert}} : insert geometry connected to selected geometry
{{knife reset}} : resets the knife starting point

Selecting

{{select single, select single add}} : select geometry
{{select paint, select paint add}} : paint geometry selection
{{select path add}} : select along shortest path
{{select all}} : select / deselect all
{{deselect all}} : deselect all

Transforming

{{grab}} : grab and move selected geometry
{{action}} : grab and move selected geometry under mouse
{{smooth edge flow}} : smooths edge flow of selected geometry

Other

{{delete}} : delete/dissolve/collapse selected
{{rip}} : rip selected edge
{{rip fill}} : rip and fill selected edge
