einvalidinput saveas

[bherber]

Hello: i have been having issue with saving drawings in Mechanical 2013,  when i debug the code below i am getting a einvalidinput on the Database.SaveAs() method. i currently run the same code on mechanical 2012 and it works fine.  please note i need to save the files in Mechanical 2012 format.  If i use DwgVersion.Current it works without erroring out but i need it to save in the Mechanical 2012 format.

using

ACE = Autodesk.AutoCAD.EditorInput;

using

ACAS = Autodesk.AutoCAD.ApplicationServices;

using

ACR = Autodesk.AutoCAD.Runtime;

using

ACDS = Autodesk.AutoCAD.DatabaseServices;

        ACAS.

Document acDoc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;

if (File.Exists(FileLocation))

                {

if (FasMain.InputBox("Drawing File Exists", "This Drawing File Exists, do you want to overwrite?", ref value) == DialogResult.OK)

                    {

                        acDoc.Database.SaveAs(FileLocation,

true, ACDS.DwgVersion.AC2To21, null);

                        ed.WriteMessage(

"\nFile is Saved");

                    }

else

                    {

                        Close();

                    }

                }

else

                {

                    acDoc.Database.SaveAs(FileLocation,

true, ACDS.DwgVersion.AC2To21, null);

                    ed.WriteMessage(

"\nFile is Saved");

                }

AC2To21 is not a valid format to save to in base AutoCAD.  It is a valid enum value, but it is not a format that base AutoCAD will save to.  Mechanical must be using that enum value to indicate something special for its own data because it still has to save to a valid dwg format which for Mechanical 2012, I think should be the same as base AutoCAD 2012 (enum value AC1024).

You can check allowed versions from list of enums like this:
Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;
Database db = HostApplicationServices.WorkingDatabase;
DwgVersion[] dws = db.GetSupportedSaveVersions();
foreach (DwgVersion dw in dws)
ed.WriteMessage("\n{0}",dw);
