Well, without trying it myself, I'd guess you could read the CGM file into Creo then save as STEP. Hopefully the type of data in the CGM file is amenable to outputting it as a STEP file.I don't have a CGM file so I can't do any testing.

According to the Help Center, CGM can be imported with Creo https://support.ptc.com/help/creo/creo_pma/r11.0/usascii/index.html#page/data_exchange/interface/To_Import_a_CGM_File.html

Yeah, I figured that if a direct CGM -> STEP converter wasn't something someone had, they could use Creo as the intermediary to translate the data. The only problem I foresee is that translation from format to format can sometimes result in inaccuracies or other weird results. The "wrong" half of an arc being written in the translated file, non-tangencies, etc.
