Converting part file to an IGS file

I have a part file I have been asked to convert to an IGS file type for my machine shop that is fabricating these pieces for us.  I converted all configurations of this part file and emailed them to him but unfortunatly, they came to him as only wire frames.  I have been asked now to convert them to IGS files with SURFACES.  How do I do this, is it even possible?
