eDrawing files (for example .easm) cannot be converted to anything else, because they are used as previews and for printing - not further editing. They are similar to PDF in their purpose. You have to access the original assembly files if you hope for export of any kind, including the one to STEP format (.stp, .step).
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.
If you find entry that you feel is flagged as bad wrongly, please tell us in the discussion below with as much as information as possible so we can fix it.
