I was wondering if there was any math to apply to the grid spacing options so I could just do an array of a line to match the existing grid. In a sense I could create a grid of lines pretty quickly.
For instance I just did an offset count of 301 to match my settings. Trial and error. what is the grid size vs. count ratio?
