It might actually be possible to export 3D models saved in VRML Worlds files (.vrl) and transform them to IGES ASCII CAD data files (.igs, .iges) with dedicated 3D/CAD conversion programs. It is likely that wrl to igs conversion can also be achieved using standard CAD programs that support both of these file types, simply via Save as.. or Export function.
