AutoCAD slide files are some kind of presentation, a set of slides made from the program screen using the mslide command. That means you cannot produce any other CAD file from it, you have to export it from the original sources which in most cases is a .dwg file. So a direct SLD to STP conversion is very unlikely, probably impossible.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
