Also, those latest developments regarding the new non-tube method of offsetting a selected edge… those too are very important. It would be good to have the method even as a seperate ‘offsetting’ tool (and even as a separate add-on).
Having a way of offsetting edges without hindrance, all over an object, is a need in Blender. It can open the way for many kinds of modelling tasks which are quite difficult to achieve by other means.
Imagine having a way to offset in an array a wavy loop all over an object: someone can make so many things with it!
