How do you offset a series of edges evenly, looped or not? Searching on line I came across http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Modeling/offset_edges which seems to be what I'm looking for but I can not get it to work using Blender v2.75. Does something have to be done to activate this? When I highlight an edge loop and hit Ctrl-E the pop-up menu does not include an 'Offset Edge' submenu.
I see this question has been asked before but the answers seem to refer to files that are no longer available.
