The title is not 100% precise, Rhino does open the PLY file but the mesh is invalid. I can select the mesh, and this is the object properties details:
mesh ID: 32b117c1-9507-495b-9248-96841afa04b8 (2717) Object name: (not named) Layer name: MeshLab ASCII pymeshlab Render Material: source = from obj index = 6 Geometry: Invalid mesh. Open polygon mesh: 225 vertices, 446 faces with normals Bounding box: (1.08132e-10,1.08132e-10,1.08132e-10) to (1.08132e-10,1.08132e-10,1.08132e-10) Geometry UserData: UserData ID: 480BCCF7-2887-4871-8385-B68894D4D9B8 description: Tibidabo Geometry Runtime Data saved in file: no copy count: 0
Hence the points and faces are all there but infinitesimally small. It could also be that VisualArq plugin is causing this.
The mesh was saved with pymeshlab. It seems that, contrary to the GUI MeshLab, it saves the vertices coords as doubles and not float. I suspect this is what is the root of the problem but I’m not entirely sure.

PS: Saving the mesh as binary does not cause the problem, which is odd. But, I’m being forced to work with ASCII for compatibility with Compas.
