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


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


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.


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.


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.
