A very light text describing the fact of plotting from different points. One of the most interesting points of which he speaks is that to trace is not only to give a path between places, but also to create places of relationship, of rest. Depending on the places that will be communicated, it will be traced one way or another, since communicating milestones is not the same as communicating neighborhoods. These points have to be studied conscientiously to trace in the cities, look for a strategy that favors this layout and attract life.
