one grid line not showing up

[Anonymous]

i am a relatively new revit user and i made the mistake of setting up my grid lines first. all of the grid lines are at 90 degrees except i had to create one single grid line that was not perpendicular. i then realized that i needed to adjust my levels and after readjusting my grid lines to the new level elevations, the one grid line that was not perpendicular has disappeared from view but still exists in the model. i would simply like to delete this grid line but i have no idea how to do it when i can't see it.

i would be extremely grateful if someone could help me get it to show back up or just tell me how to delete it (i'm assuming there must be a way to do that even if i can't actually see it in any of my views?) 

thank you!!

Option 1:  Open a view when you see all visible grids.  Select one random grid line, right click and choose Select All Instances > In Entire Project.  Then hold SHIFT key and pick all the visible grids to un-select them (you can draw a cross window from right to left while holding SHIFT if that is quicker).  You will be left with one grid and now just use DEL key to delete it.

Option 2:  Switch to an elevation.  Copy the level to the location where you had it before.  Create a new floor plan view for that new level.  You should be able to see the grid there.
