Normal Scale
Modify > Normal
Scalel
Description:
The Normal Scale (Modify > Normal Scale) tool will scale each group of
selected faces in the plane perpendicular to their respective normal
vectors. Once you initialize the tool, drag to adjust the amount
of the scale operation. You can click and drag additional times to
further adjust the scale amount. Right-click or press Enter to
exit the tool.
Notes:
- At first glance, the
Inset Scale tool might appear to be the same as the Normal Scale
tool. Too see the difference between the two, try creating a
sphere, selecting several adjacent faces, performing an extrusion (with
the faces set to stay together), and then testing both inset scale and
normal scale on the extruded faces.
