It is certainly possible to convert 3D data from IGES formats (.igs, .iges) to Autodesk Kaydara format (.fbx) with 3ds Max or even perhaps with previous versions of 3D Studio Max. But you can even find some dedicated 3D modeling conversion tools that should be capable of iges to fbx conversion just fine.
