To convert Pro/ENGINEER Render format files into Alias wire files
PRenderToAlias -h
PRenderToAlias Arguments: [<options>] [<infile> [<outfile>]] Options: -s scale Input scale factor (for example. -s2.0) -u Input units. Acceptable values are MI,FT,IN,MIL,UIN,KM,M,CM,MM,UM]. The default is -uIN -g Group the geometry -n Do not merge vertices -r Recalculate vertex normals -p Merge vertices according to xyz position only -t pos_tol Specify merge vertices position tolerance value in input units. The default is 0.0001. -a nrm_tol. Specify merge vertices normal tolerance value in degrees. The default is 1 degree. Where: <infile> is a Pro/ENGINEER Render file. If it is absent, input comes from stdin. <outfile> is an Alias wire file. If it is absent, output goes to stdout. By default all vertices are merged according to their positions and normals.
