In ArcGIS I have a feature class (lines) where i have the pipelines in. I want to create a map from that but the problem is that when i zoom out a lot of the pipelines are not visible because they are too close too each other. I know that with the use of the tool Representation you can solve this problem by making representations with different scales that connect to the original feature class. Do anyone know how this work? Im looking for this a long time but its really complicated i think. You need an advance license for this btw.
