Hi there! I am new to ArcGIS and am a bit stuck. I have a map of a park with the entrances marked on, and a network representing paths. I am trying to place an information centre within 0.5km walk of one of the entrances, travelling along the pathways. How can I show on the map where 0.5 km along the paths are, away from each of the entrances? I tried using the Make Service Area Layer but couldn't figure it out and the only tutorial I could find online said that the file was damaged and couldn't be opened. I am using version 9.3 and have ticked the Spatial and Network Analyst Extensions. Many thanks!
