Hi, I am trying to create a simple map in Illustrator CS5. I have drawn the road lines and now I want to create an outline around all the roads to make them stand out. How do I merge all the lines so that they are a single object and I do not get lines crossing at each cross roads (as happens when I use 'path outline')? The 'drop shadow' effect seems to work but I imagine there must be a more simple way. Thanks!
