该代码示例展示了如何使用NXOpen接口处理工作包文件，实现CAD图纸的自动导出和合并。程序首先读取输入文件，配置转换参数，然后调用UGTO2D和DXFDWG工具将3D模型转换为2DDWG格式，并最终使用AutoCAD进行合并。在过程中，程序会检查和处理可能出现的错误，并清理临时文件。

NXOpen入口

   class Program
    {
        static void Main(string[] args)
        {
            try
            {
                //Console.ReadKey(true);
                Console.BackgroundColor = ConsoleColor.DarkGray;
                Console.ForegroundColor = ConsoleColor.DarkMagenta;
                Console.Clear();
                Console.Title = "导出CAD图纸";

                string filePath = "";
                foreach (string arg in args)
                {
                    filePath = filePath + arg + " ";
                }
                filePath = filePath.Trim();

                CombineSheetManager manager = string.IsNullOrWhiteSpace(filePath)
                    ? new CombineSheetManager()
                    : new CombineSheetManager(filePath);

               

                manager.Commit();
            }
            catch (System.Exception ex)
            {
                if (!string.IsNullOrWhiteSpace(ex.Source))
                {
                    Console.WriteLine(ex.Source);
                }
                Console.WriteLine(ex);
                
            }
            Console.ReadKey();
        }
    }

            }

            this.mList = lines.Skip(3).Select(p => new CombineSheet(this, p)).ToList();
            if (this.mList.Count == 0)
            {
                throw new System.Exception($"工作包文件没有指定导出图纸。\r\n{filePath}");
            }
