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.
