Your best shot for work and conversion of MultiGen formats (.flt) is to use the open source Blender software. With this program you should be able not only to edit, but also export .flt files to or from several other 3D formats or 2D CAD format, including common DXF format. But of course, there may be more programs capable of this conversion.

The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned flt to dxf. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
