# Vertex connected edge highlighting

I am having an issue where the vertex that I have selected does not highlight connected edges. This happened sometime when I was modelling and it is starting to annoy me. Following this link, It says that un-checking the edge under mesh display would make the highlight disappear. I checked it and its still checked.

Loading a new file seems to display the edge highlighting and this leads to the assumption that I might have accidentally hit another shortcut that caused the edge to not highlight.

How can I fix this issue?

• Just to make sure, if you select everything do any of the edges highlight? Or is it just for that vertex? I just want to make sure that it's not just because you accidentally duplicated that vertex so it isn't connected to anything or something like that. – TARDIS Maker Jan 28 '16 at 19:00
• @TARDISMaker Selecting any other vertex results in the same issue. I have used remove doubles to remove any duplicates and the problem is not resolved. Selecting 2 edges will highlight the edge between but none other. – DarkDestry Jan 28 '16 at 19:01
• Are there any modifiers on mesh ? – Mr Zak Jan 28 '16 at 20:23

• @MrZak No, But the Mirror modifier has it on. Turning it off fixes it. Thanks. Create an answer below and ill accept it. – DarkDestry Jan 28 '16 at 20:47

In this case the vertice wasn't highlighted as expected because the Mirror modifier, which was present in stack, had button Adjust Edit cage to modifier's result turned on.
To work without this behaviour uncheck Adjust Edit cage to modifier's result in order to directly interact only with real vertices of the mesh. You can check it if needed to preview changes when it's important for the workflow.
