writing tool to add custom drawing properties

I have installed the autocad ObjectARX 2011 and .Net wizzard to start writing a .Net application for adding custom drawing parameters to all our acad drawings.  I have found two issues detailed below.  This is my first attempt at using c# with autocad so any pointers on what I am doing wrong will be well received.


1.  If add the AcDbMgd.dll and AcMgd.dll references and set copy local to false as the documentation advises then I get a FileNotFoundException, could not load file or assembly 'acdbmgd'.  If I set the copy local to true then the error goes away.


2.  I tried using the code below to add a paramater but I get an exception on the first line System.TypeLoadException: Method 'CopyTo'.


Autodesk.AutoCAD.DatabaseServices.Databasedatabase = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Database;


//Users builder to edit the summary info (file properties) of the drawing

Autodesk.AutoCAD.DatabaseServices.DatabaseSummaryInfoBuilder infoBuilder = new Autodesk.AutoCAD.DatabaseServices.DatabaseSummaryInfoBuilder(database.SummaryInfo);


string key = "test";

string value = "testvalue";


infoBuilder.CustomPropertyTable.Add(key, value);

database.SummaryInfo = infoBuilder.ToDatabaseSummaryInfo();

Hello, gbstsma


Take a look at the way I do.

I Hope that this example helps you.


My references AcDbMgd and AcMgd Path: C:\ObjectARX 2010\inc-win32

(Copy Local = False)



Create Material



using AcadApp = Autodesk.AutoCAD.ApplicationServices.Application;

privatevoid TransferirDadostoolStripButton_Click(object sender, EventArgs e)


publicvoid PopulaCustomComuns()

AcadDocument doc = (AcadDocument)AcadApp.DocumentManager.MdiActiveDocument.AcadDocument;
            doc.SummaryInfo.AddCustomInfo(textBoxD_Number.Tag.ToString(), textBoxD_Number.Text);
            doc.SummaryInfo.AddCustomInfo(textBoxRev.Tag.ToString(), textBoxRev.Text);
            doc.SummaryInfo.AddCustomInfo(textBoxLab.Tag.ToString(), tratamentoStrings(textBoxLab.Text));
            doc.SummaryInfo.AddCustomInfo(textBoxProduct_Group.Tag.ToString(), tratamentoStrings(textBoxProduct_Group.Text));
            doc.SummaryInfo.AddCustomInfo(textBoxProduct_Type.Tag.ToString(), tratamentoStrings(textBoxProduct_Type.Text));
            doc.SummaryInfo.AddCustomInfo(textBoxUnidade.Tag.ToString(), tratamentoStrings(textBoxUnidade.Text));
