Troubles in a C# interop to access a ActiveLayout.PlotType

[lfecchio]

Hi!

I doesen't acces or modify nothing in a ActiveLayout.

I'm using c# and interop and need to plot to a file a dwg.

The plot to file works well, but I need to change some properties like Plot Scale or Plot Type.

A conversion error occours.

In second place, the DefaultPlotStyleTable doesen't work too.

Somebody can helpe me?

My test code:

using System;
using System.IO;
using System.Runtime.InteropServices;
using Autodesk.AutoCAD.Interop;
using Autodesk.AutoCAD.Interop.Common;

namespace ProcessoCAD
{
   static class Program
   {
      private static Autodesk.AutoCAD.Interop.AcadApplication oAcadApp = null;
      private static string sAcadID = "AutoCAD.Application.18";

      /// <summary>
      /// The main entry point for the application.
      /// </summary>
      [STAThread]
      static void Main()
      {
         // Abre AutoCAD
         try
         {
            oAcadApp = (Autodesk.AutoCAD.Interop.AcadApplication)System.Runtime.InteropServices.Marshal.GetActiveObject(sAcadID);
         }
         catch
         {
            System.Type AcadProg = System.Type.GetTypeFromProgID(sAcadID);
            oAcadApp = (Autodesk.AutoCAD.Interop.AcadApplication)System.Activator.CreateInstance(AcadProg);
         }

         // Inicia ciclo de execução
         if (oAcadApp != null)
         {
            string StyleTable = "AZEVEDO.ctb";

            oAcadApp.Visible = true; //could leave this false to hide Acad from the user

            Autodesk.AutoCAD.Interop.AcadDocument dm; // = oAcadApp.ActiveDocument;
            
            dm = oAcadApp.Documents.Open("d:\\teste\\Teste.dwg", true, null);
            dm.SetVariable("BACKGROUNDPLOT", 0);
            dm.ActiveSpace = AcActiveSpace.acPaperSpace;
            dm.ActiveLayout.PlotType = AcPlotType.acExtents;
            dm.ActiveLayout.StandardScale = AcPlotScale.ac1_1;

            oAcadApp.Preferences.Output.DefaultPlotStyleTable = StyleTable;
            dm.Regen(AcRegenType.acActiveViewport);

            // dm.Application.ZoomExtents();
            // dm.Regen(AcRegenType.acAllViewports);
            dm.Plot.QuietErrorMode = true;
            dm.Plot.NumberOfCopies = 1;
            dm.Plot.PlotToFile("d:\\teste\\Teste.pdf", "C:\\Program Files\\AutoCAD 2010\\UserDataCache\\Plotters\\DWG To PDF.pc3");
//          dm.Plot.PlotToFile("d:\\teste\\Teste.plt", "C:\\Program Files\\AutoCAD 2010\\UserDataCache\\Plotters\\DWF6 ePlot.pc3");
            
            //dm.Close(null, null);

            //oAcadApp.Quit();
         }
      }
    }
}

Try this code snip, change to your settins and file name:

Thanks for help!

I converted the code to VB, but when it executes the line

dm.ActiveLayout = dm.Layouts.Item(0)

I have a conversion error:

"Unable to cast COM object of type 'Autodesk.AutoCAD.Interop.Common.AcadLayoutsClass' interface type 'Autodesk.AutoCAD.Interop.Common.IAcadLayouts.' This operation failed because the QueryInterface call on the COM component for the interface with IID '{9AEBED7B-03A9-4C9E-B358-4E95FA5B07F4}' failed due to the following error: No support for this interface (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

Is it because my dwg or a wrong reference?

I'm send the dwg and need to use the AR2 Layout.

Thanks

Sorry for the belating I was busy

I tested code I posted above on my machine -

 the plotting is looks good,

See plot copy log:

Job: - Plotted Job ID: 1 Sheet set name: Date and time started: 24.10.2012 20:52:47 Date and time completed: 24.10.2012 20:52:49 UserID: Олег Profile ID: <<Unnamed Profile>> Total sheets: 1 Sheets plotted: 1 Number of errors: 0 Number of warnings: 0 Sheet: - Plotted File: C:\Users\Олег\Programming\ACAD\#SNIPPETS\ACAD_INTEROP\Teste.dwg Category name: Page setup: Device name: DWG To PDF.pc3 - plotted to file Plot file path: C:\Users\Олег\Programming\ACAD\#SNIPPETS\ACAD_INTEROP\Teste_AR2.pdf Paper size: ISO A1 (841.00 x 594.00 MM)

Thanks for help!

I reinstall the ARX SDK for 2010 and works fine!

But, the DefaultPlotStyleTable insists in not work.

The code set all preferences, but the result (in pdf) doesn't reflect them.

For example, if I use the monochrome.ctb to plot into a pdf, it's doesn't plot in monochrome.

I saw too that a file stb raises a exception.

Hi!

I include the line dm.ActiveLayout.StyleSheet = "AZEVEDO.ctb" and all works fine!

Thanks for help!!!!
