I have a rather large selection of edges on a subdivided plane. I would like to have duplicate edges right next to the original ones (on the same plane). In other words, each of the original edges should have a copy right next to it, with the distances between all pairs being equal. Is it possible to select all (original edges) duplicate them and translate them along the same face/plane? The only option I found the resembles it most, is just duplicating the edges, after which the duplicates are their own mesh floating around.
In the above image, I want all the vertical lines to have a copy right next to it, as shown with the middle vertex. Is there a way to easily achieve this?
