I want to export vertices (no mesh exists) as ply file. However, after exporting the data by File->Export->.ply, the generated ply file contains no vertices. Can anyone help? I'm using blender 2.8.

Thanks in advance.

    $\begingroup$ I've submitted a patch to address that (allows to export loose geometry) 2 years ago. Unfortunately I don't have the time porting the patch to Blender 2.8x right now. However, it should still work for the latest and greatest 2.7x... $\endgroup$ – p2or Aug 28 at 15:07

Your assessment is accurate, Blender's ply exporter loops over the triangles. This can be seen in line 90 of export_ply.py.

for i, f in enumerate(mesh.loop_triangles):

Any vertex that is not part of a face isn't included in the exported mesh in Blender 2.8.
