The present specification of making LAS profile are, covert 2D map to 3D, Create profile, set profile line or box, set Depth. It works, but it is GPU intensive and heavy and slow as well as troublesome especially just checking classification results.
Simple profile function, like just set profile line and pop-up profile view, on 2D map would love to be loaded.
Even Global Mapper of Blue Marble, which is quite cheaper than ArcGIS Pro, can make profile quickly, and it is many users' favorites.
