I have to agree, writing a program may be time consuming vs purchasing a transformation suite like FME from Safe.
Other things to consider: -Autodesk devellops more GIS application everyday, like Autodesk Map , Autodesk civil, etc. now support mid/mif and .tab directly. Even Autodesk use FME for import/export capabilities so more and more user of autodesk can transform the files themselves. Also, when importing autocad files from a Autodesk gis you may have to consider elements like attributes and map objects. The object are very hard to transfer. Also, you have to consider options like wanting to transfer layers individually or in separate files? >From you email I saw that you are from Canada, Mapinfo doesn't support the Canadian >NTV2 format if you have to make transformation from one file to an other uning NAD27 >to NAD 83.

Also, From what file format of autodesk files are transforming 2004/2005, 2000/2000i/2002 R14 or even earlier versions? Etc... Can you developed this for less then a buying a already made application? Also, if it's for a commercial application, think of including the copyrights for anyone that may have done previously a similar application?

The best you can hope for is to buy MapInfo, and then use Integrated Mapping in C/C++ to open a table and then export it as DXF. An example C integrated mapping program (FINDZIP) comes with MapBasic. You can probably adapt this to perform the open/export you need (you're essentially executing MapBasic code passed into MapInfo as a string). Alternatively, third-party conversion utilities may have APIs that allow for more flexibility/streamlining of the process. Anything beyond this is like asking someone to provide you with a space shuttle assembly line for free. AFAICT MapInfo still considers the inner workings of its native data format a trade secret, and allows access to those workings only under special arrangement.
