How to run lines along the modules created on the surface vertical and horizontally to act like mullions

I want to draw lines running horizontally and vertically that correspond with the module panels created in the script so that they can act like mullions and i can delete the surface used to create it. Does anyone have advice on how to do this? lol I originally was just trying to boolean the non covered spaces out but realized this is more efficient.
