3D and OBJ formats are somewhat generic, used by many different 3D modeling / CAD programs. As such, it is not always easy to tell whenever certain program supports that particular .3d file or not. Your best bet for 3d to obj conversion of any kind would be to use some of the dedicated 3D model / CAD translation programs that typically offer broad file support.

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 3d to obj. 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.
