I have a gdb with over a thousand polylines. Recently, I've needed to add elevation data to them. I know that if I export the feature layer I can make it z aware and then use the z mode feature on scenes to automatically populate z-values for all new lines I create. However, I still need elevation values for the ones that already exist, preferably without going through all of them or mapping new lines on top of them. Each entry carries too much past metadata to make new polylines entirely.
Is there a tool that can add these values or will I have to jerry-rig something?
To be clear, I don't need the vertice z-values in the attribute table itself, but the layer does need to carry it.
