Pythagoras has all Cogo features you will ever need. Intersection, Resection, Open and Closed Traverses, Coordinate Transformations,
you name it.

More importantly, Pythagoras does Cogo in the background while-you-draw. Pythagoras accurately keeps track of the complete geometry of the drawing. All information you will ever need is derived from the geometry - coordinates, bearings, distances, slopes, angles. The geometry is a logical result of the drawing. It's always accurate, and it avoids mistakes.
