Generally speaking it should be possible to create a .dwg CAD drawing from JPEG image of technical drawing. However this requires software with some kind of tracing function (ie. that converts bitmap shapes to vectors) and heavy manual editing by the user. The result may not be stunning, it will depend on the complexity and the quality of the original image.

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 jpeg 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.
