A complete N2D model can be exported as a .Smif file, i.e., a Seismic Model Interchange File (use N2D>File>Export>SMIF Generator). This file is ASCII and contains both geometry and property information. Contact us if you want us to help you building a subroutine to convert the .Smif files into your own model files (and vice versa.) Note that a .Smif file can be imported in NORSAR-3D to generate 2.5 D models.
