@AlanW Hi Alan, that's right, they work fine first time, the issue come from when you make changes to said file and you try to update the viewport. They will often rename themselves or duplicate letters. I'm unsure how to rectify this.

Hi there, Not sure if this is the right section for questions but I've recently been having issues with the new gridline tool where it would change the numbering system from what is on the main model. For example the gridline could is 1,2,3,4... horizontal and A,B,C,D.... Vertically. However once I update my references these would change to random letters and numbers, some even doubling up its letters; I would find F where B should be and 3 where 1 should be and so on. Is this a known issue or maybe I'm using the tool incorrectly - if so where?
