I am using the ArcGIS Add XY Coordinates tool to populate XYZ values in a shapefile after converting .las data to .shp using LAS to Multipoint tool.

Does the Add XY Coordinates tool get the location info from the LAS dataset OR is it getting it from the data frame somehow?

I need to make sure I am getting the actual data from the LAS files because, I will eventually convert the shapefiles dbf to a .pts file to do some other calcs outside of ArcGIS.

Also, is there a better way of getting XYZ from LAS in ArcGIS?
