How to convert GF to IGES

[sys]

I have a hull form in GF file, I urgently need to convert this GF to IGES format with the surface information, is it possible to do this convert? Anybody knows how to do? Many thanks.

I'm not exactly sure what format GF is, but that is a pretty common extension used by GHS. If it is a GHS file, you could open the GF file in Rhino and then export to IGES.

There is no "surface" information in a GHS file. It is composed of sets of cross section curves. If you need surfaces, you will need to model them based on the curves in Rhino.

Thanks,
