⬡Mesh editing

Extrude, inset, loop cut, knife — Edit Mode tools that change vertices, edges and faces, plus the bmesh code that does the same. — 12 entries

Extends selected faces, edges, or vertices into new geometry and connects the sides.

Creates a smaller face inside the selection, leaving a border for frames and panels.

Adds a continuous edge ring across quad faces, giving precise control over where a form bends.

Knife cuts along a drawn path; Bisect cuts a mesh with a plane.

Welds nearby vertices into one, useful for duplicate points and tiny seams.

Reorients face normals consistently, usually toward the outside of a closed mesh.

Connects open edge loops with faces, joining openings or cross-sections into a tube or neck.

Rotates and extrudes a profile around an axis to create rotationally symmetric geometry.

Splits selected edges and faces into smaller pieces, increasing mesh resolution.

Removes selected edges or vertices while preserving the surrounding surface, unlike Delete.

Moves nearby unselected vertices too, with influence fading by distance and falloff.
