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.

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.

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…
