Override default commands

[annse]

Hi!

I'm trying to do something like this:

[Autodesk.AutoCAD.Runtime.CommandMethod("REFEDIT", Autodesk.AutoCAD.Runtime.CommandFlags.UsePickSet)]
public void RefEdit()
{
Document doc = AcadApp.DocumentManager.MdiActiveDocument;

if (doc is a document I care about))
{
do my stuff...
}
else
{

run the default command...
}
}

I haven't undefined the default command, my definition of REFEDIT executes anyway.

I wanna be able to run the default command from my definition.

doc.SendStringToExecute(".REFEDIT ", true, false, false); will loop forever.

Hi,

I tried this which is very similar to what you are trying and it worked ok.

With this code, the line command is redefined only for drawings that have "Test" in their name.

Can you try this and see if it works for you ?

Maybe it will then help you identify the reason for your code to loop indefinitely.

// Add reference to Autodesk.AutoCAD.Interop 
// Add reference to Autodesk.AutoCAD.Interop.Common
using Autodesk.AutoCAD.Interop;
using Autodesk.AutoCAD.Interop.Common;

[CommandMethod("LINE")]
static public void LineMethod()
{
    Document doc = Application.DocumentManager.MdiActiveDocument;
    Editor ed = doc.Editor;
    if (doc.Name.Contains("Test"))
        ed.WriteMessage("My implementation of line");
    else
    {
        AcadApplication app = (AcadApplication)Application.AcadApplication;
        app.ActiveDocument.SendCommand("_.LINE ");
        ed.WriteMessage("My implementation of line");
    }
}
    
void IExtensionApplication.Initialize()
{
    AcadApplication app = (AcadApplication)Application.AcadApplication;
    app.ActiveDocument.SendCommand("_.UNDEFINE _LINE ");
}

Thank you for your quick response!

I've added required references and I now use SendCommand instead of SendStringToExecute.

This will still loop indefinitely. (If doc.Name doesn't contain "Test")

public void Initialize()
{

AcadApplication app = (AcadApplication)Application.AcadApplication;
app.ActiveDocument.SendCommand("_.UNDEFINE _REFEDIT ");
}

[Autodesk.AutoCAD.Runtime.CommandMethod("REFEDIT", Autodesk.AutoCAD.Runtime.CommandFlags.UsePickSet)]
static public void RefEdit()
{
Document doc = AcadApp.DocumentManager.MdiActiveDocument;
Editor ed = doc.Editor;

if (doc.Name.Contains("Test"))
{
ed.WriteMessage("New refedit...");
}
else
{
AcadApplication app = (AcadApplication)Application.AcadApplication;
app.ActiveDocument.SendCommand("_.REFEDIT ");
}
}

Thanks again!

Hi,

With the Line command the code does work.

But there seems to be some problem with using it for "Refedit".

Can you check if the command is actually undefined after sending the "undefine" command ?

[Alexander.Rivilis]

What about:

app.ActiveDocument.SendCommand("_ACAD_REFEDIT.REFEDIT ");

 ?

Command _REFEDIT defined in file AcRefEd.arx

If your's dll-file loaded after AcRefEd.arx - than no need to _UNDEFINE _REFEDIT, because your command REFEDIT override standard command REFEDIT. And standard command REFEDIT can be invoked using _ACAD_REFEDIT.REFEDIT

Hi!

When I do the same thing with LINE instead of REFEDIT, my new definition of LINE won't run.

I get this error with both LINE and REFEDIT.

_.UNDEFINE
; error: no function definition: ACET-STR-REPLACE
_LINE

Thanks!

[annse]

Thanks, Alexander! That works!

My dll is loaded in a .bundle installation.

So, because I can't override _LINE the same way, _LINE is loaded after my dll and _REFEDIT before?

Thanks again!

[annse]

If the timing issue is irrelevant due to that the _REFEDIT command is already defined when my dll is loading,

I can use SendStringToExecute instead of SendCommand?

This way I won't have to echo the command.

Thanks again!

I think you can do it. Try!  🙂

Hello again...

Sending "_ACAD_REFEDIT.REFEDIT " seems to redefine the command.

If the string is executed, the next time you run REFEDIT, it'll run the default definition. 

[Autodesk.AutoCAD.Runtime.CommandMethod("REFEDIT", Autodesk.AutoCAD.Runtime.CommandFlags.Session & Autodesk.AutoCAD.Runtime.CommandFlags.UsePickSet)]
static public void RefEditDef()
{
Document doc = Application.DocumentManager.MdiActiveDocument;
Editor ed = doc.Editor;

if (doc.Name.Contains("Test"))
{

ed.WriteMessage("selected ref..");

}
else
{
doc.SendStringToExecute("_ACAD_REFEDIT.REFEDIT ", true, false, false);
}
}

Any ideas?

Thanks!

[Alexander.Rivilis]

The reason is that, in fact, AutoCAD arx-application, that handles command _REFEDIT (ie AcRefEd.arx) is loaded when you first run the command and overrides your command REFEDIT. Therefore, need to load AcRefEd.arx before your's dll-file will be loaded:

Autodesk.AutoCAD.Runtime.SystemObjects.DynamicLinker.LoadModule ("AcRefEd.arx", false,true);

 Also you can modify registry to AcRefEd.arx will loaded with AutoCAD startup:

HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\RXX.X\ACAD-AYYY:ZZZ\Applications\AcadRefEdit
LOADCTRLS = 0x02 (instead of 0x0d)

I've modified the registry. Even if I undefine _REFEDIT, my definition doesn't get called.

This code was tested with AutoCAD 2011-2013:

using System;

using Autodesk.AutoCAD.Runtime;

using Autodesk.AutoCAD.ApplicationServices;

using Autodesk.AutoCAD.EditorInput;

[assembly: ExtensionApplication(typeof(Rivilis.RefEditSubst))]

[assembly: CommandClass(typeof(Rivilis.RefEditSubst))]

namespace Rivilis

{

    public class RefEditSubst : IExtensionApplication

    {

        void IExtensionApplication.Initialize()

        {

            // Preloading AutoCAD RefEdit command arx-file

            SystemObjects.DynamicLinker.LoadModule("AcRefEd.arx", false, false);

        }

        void IExtensionApplication.Terminate()

        {

            // Do plug-in application clean up here

        }

        //------------------------------------------------

        //     Command group MUST be "ACAD_MAIN"

        //------------------------------------------------

        [CommandMethod("ACAD_MAIN", "RefEdit", CommandFlags.UsePickSet)]

        public void RefEdit() // This method can have any name

        {

            Document doc = Application.DocumentManager.MdiActiveDocument;

            Editor ed = doc.Editor;

            ed.WriteMessage("MyRefEdit..");

            if (doc.Name.Contains("Test"))

            {

                ed.WriteMessage("selected ref..");

            }

            else

            {

                doc.SendStringToExecute("_ACAD_REFEDIT.REFEDIT ", true, false, false);

            }

        }

    }

}

Very nice solution Alexander !!

Thanks!

Thank you, Alexander! Setting the command group did it.
