Force grid into rectangles

[Anonymous]

I am making a Candela building, and the problem i have is that the grid lines follow the curvature of the structure. I want it to be a normal rectangular grid. There is probably a very easy solution to it, something i've forgotten to tick off.

Thank you in advance

This is Revit 2016 btw
