How to extrude the selected faces of a cylinder symmetrically outwards? There is some way of extruding all the selected faces toward outside
 so that the extrusion is symmetrical in the object, using blender. Thanks for answer my question.



The I want is to do this in a symmetrical way, an extrusion outwards, 
I maked this selecting the faces indeviduously and extruding them outwards.
If you want to extrude all the selected faces out the same distance along their individual normals simultaneously, press Alt-E instead of E.  Hope that helps!
