Once you have created your basic map, you will be able to make some tweaks here and there.
Internet lines have curves. To create a curve on your created map, right click on the link and select Add curvature point.
If the map is too busy, raise it up a level and then create separate maps for the detail. For example, if the routers have too many interfaces that are being monitored, have a high level map to show the entire network and then have separate maps to show the different parts of the network with more detail.
Contact Iris if you need any assistance in creating a map and we will be happy to assist.
