Hi,
Around 10..12 years ago, a converter for EE-CAD formats named Ratsnest or Ratsnets was being developed, but since their constant update emails got to a level that were very spam-like, i only followed it for a year or two, until my pain threshold was reached.
I don't know if it's still out there, but it could convert between a zillion formats. Unfortunately it was far from free, beyond the betas.
I never had any real use for it though and this is more for information, in case anyone should want something like that.
