This conversion looks like something related to a 3D model to 2D conversion, i.e. exporting a slice or some 2D view from a 3D model (.obj) and saving it as DWG graphics. Apparently, this can be done using lots of different 3D modeling tools or even some dedicated converters.

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 obj to dwg. 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.
