Extruding edges
To extrude the edges interactively, drag the mouse (this changes the Offset value, i.e. the length of the
extrusion). With the mouse button still held down, you can Shift-drag to change the direction of the
extrusion. If, at this point, you still keep the mouse button held down and release the Shift key and
drag, you’ll change the Offset once more. So, by holding down or releasing the Shift key while you
drag, you can change between adjusting the extrusion length and the extrusion direction.
Extruding points
Before extrusion (left), after extrusion without the Shift key (center) and the base of the extrusion
beveled with the Shift key held down and a value greater than 0 (right).
When extruding in point mode, the points will be extruded in the direction of the point normals. The
original points at the base of the extrusion will be beveled with a value of 0 initially. You can adjust
the Bevel parameter interactively during the extrusion by holding down Shift while you drag.
Extrude Inner
Before extruding inwards. After extruding inwards.
