Thankyou Agustin, Richard, Andrea, and David for your replies! Unfortunately, I'm a newbie at this and I don't quite understand everything yet. @David: I tried using the delta from the min to the max so that all the data points were relative to 0 but got the same result. I haven't tried the

In addition to the advice you've already gotten, the reason your 3D model is so "wonky" is that you don't have elevation data outside the region you plotted, so these all have elevation zero.  Since the region is around 8500' elevation, that creates the vast wall effect

Not really. KMZ/KML is a simple dataformat not suitable for such large amounts of data. It eg does not support spatial or other indexing (even if it would, Google Earth renderering porbbably cannot use the indexes anyway)... -- Barend Köbben On 23/02/2024, 14:07, "QGIS-User" wrote: Hello, I
