I created an LAS dataset in ArcGIS 10.1 on one machine and was able to use the LAS Dataset toolbar to create profiles etc. I'm now working with the same map and files on a different machine running ArcGIS 10.5 and the LAS Dataset toolbar will not recognize the .lasd layer. The dropdown menu is grayed out even though the dataset was added to the map and present in the ToC. I tried creating a new LAS Dataset from the same LAS tiles and made sure statistics were calculated, but I still cannot get the toolbar to recognize the .lasd layer. I have all the necessary extensions authorized. Is this a problem with the v. 10.5? Thanks to anyone who can help.
