Use the "Open" command and set the approbriate Filetype (e.g. "igs" or simply "All Files").
Choose the file you want to import.
A window for setting options appears. Adapt the options and let the program work.

Don't forget to reset the filetype-selection back to inventor files next time you are using "Open"
