Wikipedia has some good information on the IGES file format which might be of use.

[Edit] There is a commercially library available which seems to be able to read and write IGES files.

You'll probably need to buy the specification (see this). Once you have the specs, you'll create one or more data structures that represents the contents of your file (always according to the specs). Then, it's just about filling the structure and writing to the file.

Its going to be very complex to try and write IGES. I'm not sure what your input is, but investigate using a 3d format converter such as Okino NuGraf to convert that input, whatever it is, to IGES. There are lots and lots of pitfalls trying to write out those 3d formats...
