Open and Edit several documents in AutoCAD

Anonymous — Fri, 06 Mar 2015 11:15:01 GMT

Hi!

I created a code that allow me to add and edit elements(entities) in AutoCAD, but it's just for a document active, and I would like to do it for several documents, I mean that my code could work into all of them

This is the code that I tried to do, and I know that i should do something else because it works for the document and stop.

Public Class ClsOpenEditDocumentsDWG
<CommandMethod("OpenEditDWG", CommandFlags.Session)>
Public Shared Sub OpenEditDWG()
Dim Path As String = "C:\Users\ladrian\Desktop\CAD'S IDIADA\Revit_CAD"
Dim FilesX As String()
If Directory.Exists(Path) = True Then
FilesX = Directory.GetFiles(Path, "*.dwg", SearchOption.AllDirectories)
For File Archivo As String In FilesX
Try
Dim AcDocMng As DocumentCollection = Application.DocumentManager
DocumentCollectionExtension.Open(AcDocMng, File, False)

Catch ex As Exception
'here the error
End Try

End If
Dim Docs As DocumentCollection = Application.DocumentManager
For Each Doc As Document In Docs
Application.DocumentManager.MdiActiveDocument = Doc
Try
EditEntities() 'Here it is my routine that process the information in a single document
Catch ex As Exception
MsgBox(Doc.Name)
End Try
'Application.DocumentManager.DocumentActivationEnabled = False
'DocumentExtension.CloseAndSave(Doc, Doc.Name)
Next

End Sub
End Class

So as I said, it just work to the first document... and stop...

I'll appreciate any help.

Thanks.

do you start from a not saved Drawing1 ?
AutoCAD might close the unused Drawing1 when opening the first (other) drawing. Then after manipulating that drawing and closing there is no docume nt anymore which might cause some problems.

Do you really need to open the drawing as a document ? You might consider to open just the Database and then
EditEntities(inThatDb)

Hi! Thanks for your answer.
I got one way to open every Doc and edit them but my problem now is try to save and close.....

About to open just the database I Don't understand because to edit a document I Have to open it, right? And the code that I created works into the active document. Please could you explain it to me little more about it.

Thanks in advance

Hi, You need to add all the documents to the collection and iterate through the loop, get the document and do your process and save as and close the document. What are problem are you facing, can I check through your code ? I can help you if you are missing something. Do let me know.

This example shows how to open the Database but not load it as a document in the AutoCAD Editor only, and then manipulate the Entities.

        [CommandMethod("TestOpenDb")]
        public void TestOpenDb()
        {
            Document doc = AcadApp.DocumentManager.MdiActiveDocument;
            Database db = doc.Database;
            Editor ed = doc.Editor;

            string dwgPathname = @"c:\temp\x.dwg";
            try
            {
                if (!File.Exists(dwgPathname))
                    throw new System.Exception(string.Format("File not found: {0}", dwgPathname));

                 using (Database dwgDb = new Database(false, true))
                {
                     //Open Database but not "visible" in AutoCAD Editor
                    dwgDb.ReadDwgFile(dwgPathname, FileShare.Read, true, null);
                    dwgDb.CloseInput(true);
                    EditEntities(dwgDb);
                    dwgDb.Save();

                }

            }
            catch (System.Exception ex)
            {
                ed.WriteMessage(ex.Message);
            }

        }

        public bool EditEntities(Database db)
        {

            using (Transaction tr=db.TransactionManager.StartTransaction())
            {
                // 'Here it is my routine that process the information in a single document
                tr.Commit();
            }
            return true;
        }

Thanks for all help Guys!

At the end, becuase there were serveral problem to save de database I used this:

DWGDB.SaveAs(DWGDB.Name, DwgVersion.Current, DwgVersion.Current, DWGDB.SecurityParameters)
