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.
