NAME

       ivdowngrade - converts Inventor 2.1 files to the Inventor 2.0 and 1.0 formats

SYNOPSIS

       ivdowngrade [-v targetVersion] [infile outfile | infile ]

DESCRIPTION

       ivdowngrade  reads  the input file infile and converts it to the Inventor format specified
       by -v targetVersion , either 1.0 or 2.0. If the -v option is not  specified,  an  Inventor
       V2.0  file will be generated. The input file can be in Inventor or VRML format. The output
       will always be in ascii format.  If no output file is  specified,  ivdowngrade  writes  to
       stdout. If no input file is specified as well, ivdowngrade reads from stdin.

EXAMPLE

       ivdowngrade -v 1.0 foo.iv moo.iv
             Downgrades the file foo.iv to Inventor V1.0 format, writing to moo.iv.

       ivdowngrade goo.iv
             Downgrades the file goo.iv to Inventor V2.0 format, writing to stdout.

NOTES

       Because  of differences between the 1.0 and 2.0 file formats, some data may be lost during
       the conversion to 1.0. For instance, the 2.0 file format for SoSeparator  contains  fields
       for  caching  and  culling,  but  the  1.0  format  for  SoSeparator  has  no fields. This
       information is lost during the conversion process.
       No data is lost going from the 2.1 to the 2.0 format.
