			CSharp啟動AutoCAD
		
            
		

            一 我們可以通過AutoCAD安裝以后提供的COM接口啟動AutoCAD。

            COM組件為： 
            AutoCAD/            ObjectDBX             Common 17.1 Type Library (Autodesk.AutoCAD.Interop.Common.dll). 
            AutoCAD 2009 Type Library (Autodesk.AutoCAD.Interop.dll)                

            二 方法一
            

                    public static void Way1()
                                {
                                    const string progID = "AutoCAD.Application.17.1";
                        AcadApplication acApp             = null;

                                    try
                                    {
                            acApp             = (AcadApplication)Marshal.GetActiveObject(progID);

                        }
                                    catch
                                    {
                                        try
                                        {
                                Type acType             = Type.GetTypeFromProgID(progID);
                                acApp             = (AcadApplication)Activator.CreateInstance(acType,true);
                            }
                                        catch
                                        {
                                MessageBox.Show(            "Cannot create object of type \"" +progID + "\"");
                            }
                        }
                                    if (acApp != null)
                                    {
                                        // By the time this is reached AutoCAD is fully
                                        // functional and can be interacted with through code
                            acApp.Visible = true;
                            acApp.ActiveDocument.SendCommand(            "_MYCOMMAND ");
                        }                    
                    }
            

            三 方法二

            

                    public static void Way2()
                                {
                                    const string progID = "AutoCAD.Application.17.1";
                                    const string exePath = @"E:\Program Files\Autodesk\ACADM 2009\acad.exe";
                        AcadApplication acApp             = null;

                                    // Let's first check we don't have AutoCAD already running
                        try
                                    {
                            acApp             =(AcadApplication)Marshal.GetActiveObject(progID);
                        }
                                    catch { }
                                    if (acApp != null)
                                    {
                            MessageBox.Show(            "An instance of AutoCAD is already running.");
                        }
                                    else
                                    {
                                        try
                                        {
                                            // Use classes from the System.Diagnostics namespace
                                            // to launch our AutoCAD process with command-line
                                            // options
                                ProcessStartInfo psi = new ProcessStartInfo(exePath, "/p myprofile");
                                psi.WorkingDirectory             = @"c:\temp";
                                Process pr             = Process.Start(psi);

                                            // Wait for AutoCAD to be ready for input
                                            // This doesn't wait until AutoCAD is ready
                                            // to receive COM requests, it seems
                                pr.WaitForInputIdle();

                                            // Connect to our process using COM
                                            // We're going to loop infinitely until we get the
                                            // AutoCAD object.          
                                            // A little risky, unless we implement a timeout
                                            // mechanism or let the user cancel

                                            while (acApp == null)
                                            {
                                                try
                                                {
                                        acApp             = (AcadApplication)Marshal.GetActiveObject(progID);
                                    }
                                                catch
                                                {
                                                    // Let's let the application check its message
                                                    // loop, in case the user has exited or cancelled
                                        Application.DoEvents();
                                    }

                                }

                            }

                                        catch (Exception ex)
                                        {
                                MessageBox.Show(            "Cannot create or attach to AutoCAD object: "+ ex.Message);
                            }
                        }

                                    if (acApp != null)
                                    {
                            acApp.Visible             = true;
                            acApp.ActiveDocument.SendCommand(            "_MYCOMMAND ");
                        }

                    }
            

            四 當(dāng)然也可以使用C++去調(diào)用COM接口。
