    TIG:
    Last time I looked, ThomThom's Selection Toys only selected face loops, that is loops composed of faces, not loops composed of edges. I do think his tools will select edge loops totally contained within a face.

    Anyway, a girding edge loop would allow quick selection and you could scale it, move it copy it and so forth.

    Soon as somebody figures it out, the next step would be loop subdivide like Blender has.

    By the way, would the topic title need to be edited? From "delection" to "selection"?

    I take the slow, deliberate approach in my aimless wandering.

      I've seen this request a number of time - but I wonder do people have such clean geometry that it actually works. These other 3D apps to which people refer to usually allow for non-coplanar quads. While SU doesn't do this - significantly decreasing the usability for such a selection feature. The geometry need to be regular in its construction in order to determine the direction of the next edge to select.

        Probably a gross over-simplification, but can't you grab the next connected edge whose angle between the current edge is less than a specified angle?

        As you say, regular geometry is required. It would not work so well on sub-divided mesh.

          Hi TIG,

          You're correct, "ThomThom's Selection Toys only selected face loops, that is loops composed of faces".

          Hopefully someone will manage to figure out a script for that plugin.

          Thanks,

              It's pretty easy to switch to wire-frame or Xray mode and position your camera to view 'side on' and then use select by fence with left-right drag so only things that are wholly inside the fence get picked [as opposed to right-left drag fence making which selects everything that has just a part of itself inside the fence]
              Voila! you have the loops edges selected in 'one foul swoop'.
              If you do select something that's not wanted then remove it from the selection-set by holding down shift+ctrl and re-picking it... ❓ 💭

                Fredo's Hover Select has an option to "Extend selection to cofacial and aligned edges". It works to do a loop select on clean quads. Another option would be a script that I think Jim or TIG helped me with a while back called Select Edges by Z. You can pick an edge and run the script and it will pick all other edges on that Z coordinate.

                  Hi TIG,

                  Yes, that's a method I use sometimes, but it works on simple shape like the example I showed or on model with a few details. I was hoping for a plugin that will quickly help select edge loops on complex models.

                  Thanks though.

                  Have a great day! ☀

                    Hey Adam,

                    Thanks for the tips. I tried it but did not work so well as my model is quite complex and has lots of details.

                    Take care,

                      I know this is an old post to bump, but in case someone finds it my new plugin was written to do this exactly:

                        Thanks for the extension that you have included.
                        would it be possible to tweak it to just include "connected edges"?

                            SketchUV and Profile Builder have this tool

                              On the quadface tools, there is select loop button.

                                Brilliant!, I have quad tools 'select' set on a shortcut. Just right click on the line and select 'selection'-> 'select loop'.
                                Many thanks, cengizileten

                                  I´m a bit late to the party, but... While Twilight render has other main purpose, looks like in the Pro version it has tools that allows to select edge loops: https://www.twilightrender.com/index.php/component/content/article?id=187:twilight-render-tutorials-tools

                                  Hope that helps.
