ArcPro: how to select a data point within a depicted las file

[KenLucas]

I have an las file depicted in map3D view, with the 3D Analyst ext active. I have the las file selected in the contents pane and I can't select a data point, using the select tools.

Hello Ken, LAS points can be selected using the selection tools on the LAS dataset layer's Classification tab in the ribbon. The selection will be enabled for the LAS points that are being drawn in full resolution. In the scene view, the full resolution LAS points will be displayed with their usual symbology, while the ones that are not in full resolution will be displayed drawn in a faded, off-white color.
