When you want to open a ECAD file in Creo there will be two formats given by electrical people ie.emn and emp file. First select emn file and then automatically it will ask for emp file to be opened and after that it will ask for the option whether you want all the holes and so on because electrical people would have given more holes for their routings but if we import all those holes it may take longer time. So suppress those holes by giving the option none. Then the ECAD file will be imported into CREO successfully.
