Thanx in advance. Come on now, give us a fighting chance. What does "Connected in a particular fashion" mean - are they brothers? Are the white lines straight lines or curved lines? If you can't be bothered to phrase a meaningful question, you can't blame us for not bothering to phrase a meaningful answer. Put the image up on one of the image sharing sites so we can get a look at what you are failing to describe using words, maybe we can get an idea from that. A pure shot in the dark here, assuming the lines are straight type the following at your command prompt help hough Regards Dave Robinson

Now if I want to assign a different color to each edge how can i do it. Based on the same lines I have two curved pipes intersecting each other. So I have 4 curves which I have shown on image sharing site. I want to assign 4 different colors to each curve. I hope I have made myself clearer. Thanx.
