The function ConcaveHullMesh was introduced in V13. Great, I thought. However, the function appears to work only with 3D {x,y,z} points. I therefore understand that whilst the function will return a 3D volume mesh, it’s unable to return a 2D mesh if given a list of {x,y} point coordinates. I’ve tried ‘tricking’ the function by providing it with a list of {x,y,z} points with all the z values set to zero, but without success.

It seems odd that this function is limited to operating on 3D points, especially given that the FunctionRepository function NonConcaveHullMesh works for both 2D and 3D points.

Am I missing something?
