when in plan view ur axis divides the entire spaace into 4 QUADRANTS.. so the left upper quadrant is the NE quadrant... considering the NS-EW direction!
one of the first basic things u learn in engineering drawing!
Do you mean the upper left, or am I confused. Looking at a map, NE would be the upper right. That's also the quadrant (octant?) within the darker axes lines.
When I took engineering drawing we used graphite sticks encased in wood and rubbed them on pressed wood pulp.
