Extrude

Extrude

This tool extrudes selected points, edges or polygons. If no elements are selected, all of the object’s elements will be extruded.

To extrude interactively in the viewport, drag left or right within the viewport. The extrusion takes place along the Normals of the selected surfaces; the average value is evaluated from all the Normals to be extruded.
