DxfToIv(1)

NAME
     DxfToIv - converts an Autodesk Data Exchange File format (.DXF) file to
     Open Inventor 2.0 format

SYNOPSIS
     DxfToIv [-b] [-h]
             [-v] [-q]
             <infile> <outfile>

DESCRIPTION
     DxfToIv converts 3D model files in Autodesk DXF R12 format into Open
     Inventor 2.0 files. The program converts ASCII or binary .DXF format.
     Polygons, polylines, and certain versions of text are converted into
     equivalent Open Inventor objects. The DXF file divides the objects into
     layers and/or blocks. These layers and blocks are converted into Open
     Inventor separators so all DXF entities in a given layer are placed under
     one Open Inventor separator node. DXF text entities that refer to an
     AutoCAD .shx (font) file are not handled. Text that is defined within the
     DXF file is converted. Copyright (c) Silicon Graphics, Inc. 1995 and

   Command Line Options
     Typically, DxfToIv expects an Autodesk DXF file to be specified on the
     command line after all command option switches. If no .DXF file is
     specified on the command line, DxfToIv will read from standard input
     (stdin).  By default, DxfToIv writes the converted data to standard
     output (stdout) and messages to standard error (stderr).

     -b        Output the Open Inventor file in binary format.

     -h        Prints a program usage message to the standard error (stderr).

     -v        Specifies verbose output for debugging purposes.

     -q        Specifies quiet mode.  In quiet mode, no output is written to
               stderr, including the copyright notices.


     <infile>  Specifies the name of the file to read and convert to Open
               Inventor.  If "-" is specified instead of a filename, input
               will be read from
                standard input (stdin).  If no file name is specified, the
               program will be read from standard input (stdin) and output
               will be written to standard output (stdout).


     <outfile> Specifies the name of the Open Inventor file to use for output.
               If no file is specified, the program will output to the
               standard output (stdout).
KNOWN BUGS
     1.  16-bit (BIGFONT) shape data, including Kanji Text, is not handled

     2.   Some Intergraph Microstation DXF files are not completely handled,
          especially if containing "exploded" views.

     3.   Non-standard DXF files may not be handled properly. The translator
          is written to convert AutoCAD DXF files as ouput by AutoCAD and does
          not handle every possible DXF file. Problems are handled by: layer
          names with spaces, missing header information, decimal points in
          integer fields, etc.
