I can import a .ply file and it gets imported and displays in 3D: you can grab it and move it around to take a look at all sides. When I try to ReliefPlot the imported object (object = Import["pathname/filename.ply"] the original is 46meg) I get the error message: Argument at position 1 is not a 2 x 2 or larger numerial matrix of real values. I tried copying ReliefPlot[ Import["http://exampledata.wolfram.com/hailey.dem.gz";, "Data"], ColorFunction -> "GreenBrownTerrain"] from the Basic Examples of ReliefPlot, substituting my file, but "Data" is not an available element of .ply files. When I tried DataFormat, which IS in the .ply Elements list, I got a list of {Real32, Real32, Real32} as Argument 1 in the error message. Howard Fink
