Drafting error of detail points on a station affects directly its precision in conditional large-scale topographic survey since the means came along so that cartesian coordinate mapping is put forvoard. Through analyzed, the mapping could highten detail points precision. This paper points out the drafting of detail points to has higher precision using graduate set-square after transforming the coordinate of detail point to coordinate by square net as a origin.
