Clockwork has a node to place spot elevations. I originally wrote it for plan views but I recently modified so it’s possible to place spot elevations in other view types as well. Haven’t tested it thoroughly, though. The modified version will be in the next release, but you can download it here: https://raw.githubusercontent.com/andydandy74/ClockworkForDynamo/master/nodes/1.x/SpotElevation.ByPoint.dyf
