Use the Mapcheck command to check your figure for length, course, perimeter, area, error of closure, or precision information.
Calculate closure, precision, perimeter, and area using the listed distances, courses, and units based on the current drawing unit precision set.
The Mapcheck report starts at the beginning of the figure. For each segment, based on the Linear and Angle precision (set in the Survey Database Settings) then the next figure vertex XY coordinates are computed based on the inversed direction and distance/curve data (rounded to the Linear and Angle precision values). For closed figures, due to the fact that error is introduced into the sequential computation of vertices of the mapcheck report, a closure error, closure direction, and precision can be calculated. The area is also based on the computed vertex XY coordinates.
