- INTRODUCTION
- ============
-
- DXFIX is an open, programmable application which generates ASCII or
- binary DXF files compatible with any release of AutoCAD.
-
- The information in this file provides the basic instructions for
- translating R13 DXF files to R12. This translation is controlled by
- translation specification files (DXT files) which can be modified to
- suit the user's needs.
-
- For additional information regarding DXF translations and information
- on modifying DXT files, see DXFIX.DOC. Also, the DXT file contains
- comments regarding the translation of specific objects.

- HOW TO TRANSLATE A R13 DXF FILE TO R12
- ======================================
-
- To translate a Release 13 DXF file to Release 12 format, use the
- following syntax at a DOS prompt:
-
- dxfix [-a<digits>] -t<name> <infile> <outfile>
-
- Where <infile> is the input DXF file name (an extension of .dxf is
- assumed if no explicit extension is given), and <outfile> is the
- output DXF file name (.dxf is also added to this name if no extension
- is present). The input DXF file can be either binary or ASCII format;
- binary format is faster to process and maintains full accuracy of
- drawing objects, but if you supply an ASCII DXF file, DXFIX will
- process it without difficulty. DXFIX reads binary DXF files written
- in AutoCAD portable format regardless of the system on which it is
- running, and ASCII DXF with any of the end of line conventions
- recognized by AutoCAD.
-
- The <outfile> is written, by default, in binary DXF format. When
- transferring data to AutoCAD Release 12, this format is preferable by
- far as it is much faster to write, generally smaller, and preserves
- full accuracy. If you want ASCII DXF output instead (for example, if
- the DXF is intended for an AutoCAD prior to Release 10 that only
- supports ASCII DXF, or is being sent to a non-Autodesk DXF processing
- program that requires ASCII), specify the -A<digits> option, where
- <digits> is a number giving the precision, in decimal places, to which
- numbers should be edited in the ASCII DXF file.
-
- The -T<name> option specifies a translation specification file name.
- The translation specification file tells DXFIX how to translate the
- DXF file. To translate R13 DXF files to R12 DXF you must specify the
- dxfix13.dxt file. If this option is not used it defaults to dxfix.dxt.
- The .dxt extension is assumed if not specified.
-
- For example, to convert a binary Release 13 DXF file named "house13.dxf"
- to a binary Release 12 DXF file named "house12.dxf", use:
-
- dxfix -Tdxfix13 house13 house12
-
- To perform the same translation, but generating an ASCII output file
- with six decimal places of precision, use:
-
- dxfix -A6 -Tdxfix13 house13 house12
-
- The DXFIX.EXE file supplied will run on both DOS and in a DOS window
- under NT. This executable can also be used to convert ASCII release 12
- files to 10 using the original DXFIX.DXT (not supplied here). However,
- due to a change in the size of a code field, it cannot be used to
- convert binary Release 12 to 10 files. To do that you must use the
- original DXFIX.EXE (also not supplied here).
-
- For a description of the changes to convert an R13 DXF file to R12
- format please see the comment at the top of DXFIX13.DXT.
