Navisworks - Convert NWC/NWD to DXF via FBX using C#

[IPrtk]

Problem statement

I am trying to export the NWD file to DXF via C#.

What have I done till now?

I have created a plugin to call this below method POCMethod(string pa) which exports the active document to FBX. After the file is converted to FBX, I am planning to convert the files to DXF using some DLLs of 3D Max.

public class ExportNWDAsDXFPlugIn : AddInPlugin
{
	public override int Execute(params string[] parameters)
	{
		if (!string.IsNullOrWhiteSpace(nwdFilePath))
		{
			if (result == true)
			{            
				POCMethod(nwdFilePath);
				return 1;
			}
		}
		return 0;
	}
	
	private void POCMethod(string pa)
	{
		try
		{
			PluginRecord FBXPluginrecord = Autodesk.Navisworks.Api.Application.Plugins.FindPlugin("NativeExportPluginAdaptor_LcFbxExporterPlugin_Export.Navisworks");

			if (FBXPluginrecord != null)
			{
				if (!FBXPluginrecord.IsLoaded)
				{
					FBXPluginrecord.LoadPlugin();
				}
			}

			Plugin FBXplugin = FBXPluginrecord.LoadedPlugin as Plugin;
			FBXplugin.GetType().InvokeMember("Execute",
				System.Reflection.BindingFlags.InvokeMethod,
				null,
				FBXplugin,
				new string[] { pa });
		}
		catch (Exception ex)
		{
			throw;
		}
	}
}

Problem

1. I am selecting a file as an active document in the Navisworks editor window and executing this plugin. The popup window showing the conversion percentage is displayed, but the exported file is not saved in the file path.
2. This plugin requires to manually load the document in the editor context. But I need to run the conversion for multiple Navisworks files in a folder location. Any suggestions on how that can be achieved via C#?

If you want convert multiple files, call Roamer.exe with proper arguments for each file.

Can you point me to any similar implementation to convert FBX to DXF using 3DS Max?
