As far as we know, conversion of EASM CAD files to IGES format is not possible. You need the source from which the EASM files was made and then save the assembly file in Solidworks to something useable in other CAD software.
This conversion entry was verified by us and conversion was flagged as wrong or not possible.
Usually this happens when the conversion would try to convert different types of data between each other, such as audio to image, or it is not possible because incompatibility between programs, caused by closed file formats, very limited support etc.
