as the names says... it imports PLY-files (ascii/binary, big & lil endian)
 here you find some files to import:
 The Stanford 3D Scanning Repository
 Large Geometric Models Archive

file content

import normals

import vertex colors

import texture coordinates

import materials

replace or add to scene

name of imported object

flip axis, (Z is up)

center pivot, or it will be at [0,0,0]

scale imported object

all faces get same smoothing-group

 PLY-files can be huge, don't blame me if Max runs out of memory and quits :)
