Dear Florent and Wolfgang, Thank you so much.
Both of your method work well. I have another question. path p; P := z1—z2—z3—cycle; drawarrow p; It draw arrowhead at the last edge only. To draw arrowhead of each edge, I draw edges one by one. Is there a simple way to draw arrowhead of each edge? Thanks again.
