I knew it was imminent, but didn't know it was that imminent. Perhaps try ConcaveHullMesh in 13.1? The documentation example works for me fine in 13.1 beta. I didn't have time to get 13.1 final yet…

Thanks Sander. I think you’re right. It looks like the documentation has gotten ahead of the software. I’ve not noticed this happen before. But presumably it means the release of 13.1 is imminent.

Agreed, That was one of the first things I checked. V 13.0.1.0. The issue is, there seems to be a V 13.1. But I don’t see that version available for download in my user portal. And the function ConcaveHullMesh doesn’t appear to work as described in the online documentation.
