I would like to rotate Point features along a line feature. The angle should be calculated depending on closest selected line feature. E.g. valves along a water conduits. The valves are in one Point feature class and the water conduits are in a polyline feature class.
I have heard that this is part of the Cartographic representation Tools, but could somebody help me with a more precise description?
Not sure, but the Align Marker To Stroke Or Fill (Cartography) tool may be what you are looking for:
ArcGIS Help (10.2, 10.2.1, and 10.2.2)
It requires an Advanced (ArcInfo) license.
