This tool is similar to Extrude Faces(面を押し出し), but instead of moving all vertices along the same axis, it moves each vertex along its normal. This means an outward extrusion on a convex surface will make the faces larger, for example.

Before extrusion

Regular extrusion

Extrusion along normals

After extruding, the following options are available in the Adjust Last Operation(最後の操作を調整) panel:

Flip Normals(法線を反転)

Flip the normals of the newly created faces, as they might be pointing the wrong way depending on the extrusion direction. See the Face Orientation(面の向き) overlay of the 3D Viewport to check whether they are correct.

Dissolve Orthogonal Edges(直交する辺を溶解)

When enabled, newly created faces will be merged with surrounding existing faces (potentially turning them into n-gons) if they form a flat surface together.

Offset(オフセット)

Distance to move the vertices.

Offset Even(均一オフセット)

When disabled, each vertex is offset by the same distance. When enabled, each face is offset by the same distance.

This option can also be toggled while extruding by pressing S or holding Alt. (These shortcuts are shown in the status bar.)

Before extrusion

Offset Even off (default)

Offset Even on

Mirror Editing(ミラー編集)

Enabling this option moves the corresponding vertices on the other side of the mesh without extruding any faces, making it not very useful here.

Proportional Editing

Enabling this option also moves the surrounding unselected vertices along their normals, making it not very useful for extrusion.
