So I made an edge loop on horizontal along size the whole side of this object as you can see in the front, and where it is in red that is me extruding the selected face. However, I messed up and had to delete bunch of geometry and then re-add it (that very long rect on right side is what I redid). So then I wanted to basically re-do the edge loops I made and extend them to this re-done geometry.
So I went and started to dissolve edges on the faces, but did not realize that the edge loop was still there, and was wondering why I couldn't re-add edge loop, until I extruded this face and saw that I only dissolved the visible side.
So my question here is, either A) How do I easily recombine my geometry (even the not so visible sides) or B) how to I "extend" the edge loop to these faces I dissolved them on.
