Extending Unigraphics NX using C# (I) Manual approach

• Create a library project in C#;
• Add a class with 2 methods like below:

  class TestAtt
    {
        public static void Main()
        {
            Session theSession = Session.GetSession();
            theSession.ListingWindow.Open();
            theSession.ListingWindow.WriteLine("Running the Sample Application");
            MessageBox.Show("Good");
        }

        public static int UnloadLibrary()
        {
            return (int)Session.LibraryUnloadOption.Explicitly;

        }
    }

• Add reference dll in UGDir\UGII\managed\ to the project
• Add “using NXOpen; using NXOpen.UF;” in the class file
• Add the NXSigningResource.res to the project, configure the Build Action as “Embedded Resource”

• In the post-build event, type “SignLibrary -verify $(TargetPath)” to sign the dll.

Note that the last 2 steps are not necessary if you only run the extension plugin/addin on your local computer, however they are required if you want to run on other computers. For more details, refer to NX Open Programmer’s Guide  at UGDir/UGDOC/html_files/nxopen_prog_guide/index.html

• Compile and build, a dll will be generated.
• Open UGNx, press Ctrl +U, browse to the folder where the DLL resides, click the DLL, and the DLL will be loaded.

That is it. Happy coding!
