### 9.5.1. Introduction

BladeGen now supports a more complete interface for user specific import and export. This interface allows the user to export mean line data to a user specified file format. The user can also import a blade from mean line data or data that can be converted to mean line data.

The interface requires the user to compile C++ functions using Microsoft Visual Studio C++ 11.0, and link the object(s) with the supplied main.obj and libraries.

The interface is defined by a supplied main.obj file that has the main function for the program. This function provides a functional interface, as shown below, and a hidden support interface for BladeGen to access information from the program.

The following is returned from the main function when the program is executed without parameters. It describes the interface and displays the BladeGen file version number supported by the interface. This file version number must be greater or equal to the number created by BladeGen for the export function to work. The import function is not as dependent on the file version number, as BladeGen can read old file formats.

    MeanUIO.exe - File #029
    Syntax:
            Import: MeanUIO.exe -i [bgd_file] [user_path]
            Export: MeanUIO.exe -o [bgd_file] [user_path] {source_name}
