eDrawing files (.easm) typically cannot be converted to anything else, because they are used as previews and for printing - not for further editing, which makes any easm conversion troublesome - including export to IGES format format.
If you need STEP CAD data from a Solidworks drawing, you need to have the original exported as IGES (.igs, .iges). Some versions of eDrawing also allow the author to "unlock" the files for further use.
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.
