Autodesk Inventor supports export to plenty of other 3D modeling / CAD formats, including IGES 3D exchange format (.igs, .iges). So the easiest and most reliably way to convert .idw to .igs would be to use the original tool. Some viable alternative would be to use some other, 3rd party 3D modeling or CAD tool with support of Inventor's formats.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
