Hello! Student in engineering. I just saw an autocad drawing that confused me. Coordinates were listed as "N. 2+200" for example, but then coordinates within the grid (for the design) were in x and y coordinates. Can someone help explain what the numbers and + sign mean? Does this have something to do with a specific way to write northings and eastings coordinates? Or does it have to do with station in autocad? Thank you in advance!
