Hi All,

I am trying to run the below code which I got from theswamp.org website but its not working, kindly can anyone highlight the issue and try to solve it.

EXPORTLAYOUTS command example (theswamp.org)

[CommandMethod("EXPORTLAYOUTS")]
public static void ExportLayoutsCommand()
{
var doc = Application.DocumentManager.MdiActiveDocument;
var db = doc.Database;
var editor = doc.Editor;
try
{

// check if drawing saved or not
if ((short)Application.GetSystemVariable("DWGTITLED") == 0)
{
editor.WriteMessage("\nCommand cannot be used on an unnamed drawing");
return;
}
string format =Path.Combine(Path.GetDirectoryName(doc.Name),Path.GetFileNameWithoutExtension(doc.Name))+ "_{0}.dwg";
editor.WriteMessage(format);
string[] names = null;
using (Transaction tr = doc.TransactionManager.StartTransaction())
{
// Get the localized name of the model tab:
BlockTableRecord btr = SymbolUtilityServices.GetBlockModelSpaceId(db).GetObject(OpenMode.ForRead) as BlockTableRecord;
Layout layout = btr.LayoutId.GetObject(OpenMode.ForRead) as Layout;
string model = layout.LayoutName;
// Open the Layout dictionary:
IDictionary layouts = db.LayoutDictionaryId.GetObject(OpenMode.ForRead) as IDictionary;
// Get the names and ids of all paper space layouts into a list:
names = layouts.Keys.Cast<string>().Where(name => name != model).ToArray();
tr.Commit();
}

@Ahmed_204

you have to reference AcExportLayout.dll you found it in the same location of acdbmgd.dll.

Hi @essam-salah ,

After I referenced AcExportLayout.dll , Exportlayout2 worked fine but my issue now while trying to use EXPORTLAYOUTS I am receiving the below error.

._EXPORTLAYOUT Autodesk.AutoCAD.Runtime.Exception: eInvalidInput
at Autodesk.AutoCAD.ApplicationServices.Core.Application.SetSystemVariable(String name, Object value)
at Export_Layout.ManagedSystemVariable.Dispose() in H:\AutoCAD Building Add-ins with C#_LinkedIn Course\My Autocad Projects\Export Layouts\Export_Layout\myCommands.cs:line 356
at Export_Layout.MyCommands.ExportLayoutsCommand() in H:\AutoCAD Building Add-ins with C#_LinkedIn Course\My Autocad Projects\Export Layouts\Export_Layout\myCommands.cs:line 141

Thanks for your support.

@Ahmed_204

yes it gives the same error, and the problem is in line editor.Command("._EXPORTLAYOUT", filename);

and i think it's a common problem in autocad sending comman with parameters.
