Hi, Right click the layer and go to symbology and then go to edit symbol. At the top, under properties, from the type dropbox, select cartographic line symbol. select the line in layers window on the left and on the right select "Arrow at end" what ever suits you. regards, Thank you for your response. but, it seems that, If I am doing it right, this does not give me the direction as an attribute.It just changes the lines to arrows! I know the direction of the lines, but I need it to be added as a column to the attributes of the links. Since there are so many links, it is not feasible to do that manually. thanks again
