I have an object that I tried making a loop cut on and bringing up the new cut all the way toward the top. However, the new edge stops before reaching the location that I want to put it, it cannot go all the way to the top or to the bottom of the object. It won’t let me slide it any further. Thinking I might have bumped a setting somewhere I restarted Blender and tried a loop cut on the default cube. Sure enough, the new loop cut could be moved wherever I wanted, even directly over the original vertices. I appended my original object from my other file and tried again, with the same result. I couldn’t get the cut where I wanted it.
Does anyone know what might be causing this on certain objects but not others? Did I do something to my object?
