I want to use a topological autorouter like TopoR. This requires the export of any of the following formats: eagle (.brd) / specctra (.dsn / .edf) / PCAD ASCII (.pcb) / PADS ASCII (.asc) / Expedition PCB (.hkp). I think .brd or .dsn would be preferred for the majority of users. Is it possible now? There is something besides .json and gerber? If not - whether it is planned?
