I know that blender has extrude along an axis, but is there a way to extrude along normals?
i hope i’m wrong, but i’d say - no.
if you extude no distance, then scale along normals you can get the same effect
alt+s [scale along normals]
hm, neat trick glad i was “wrong”
Look for “Extrude along Normals” script by (I think) Tuinbels and “Tesselate” by jms.
