I believe that to perform the meshing of a cloud the LSQ plane is computed and the points are projected onto this plane. A delaunay 2d mesher is then invoked.

In the process of projecting the points i would imagine that points could project at or very near previous locations which may cause problems with the meshing. How do u avoid these situations?

Thanks for any clarifications.

Well, that's one of the 2 options you have when you use the '2.5D Delaunay triangulation' tool. The other option is to not project the vertices on the best fitting plane, but on the XY plane by default.

In any case, that's the meaning of '2.5D'. During this projection, vertices should not fall/project on each others. Otherwise it means it's actually a 3D cloud and this method won't work properly.
