Need Help with Batch Flatten Command

[Anonymous]

Hello,

I've been trying to create a script that opens a dwg file, performs the flatten command, and saves a copy of the file with "_TOP" appended to the original file name. Right now I am just trying to get one file to work. I can get a file to open but cannot seem to call the flatten command before lDoc.Save(); I know from some research that SendStringToExecute runs async to the given process, but is there a way to force to to run synchronously with other functions?

Any help would be appreciated, thank you!

var lFileName = "C:\\Users\\KDhyne\\Desktop\\DWG Testing\\4821410SA2.dwg"
var lNewName = $"{Path.GetFileNameWithoutExtension(lFilePath)}_TOP.dwg";
var lDoc = ACAD.DocumentManager.Open(lFileName, false);
using (DocumentLock docLock = lDoc.LockDocument())
{
   lDoc.SendStringToExecute("zoom all ", true, false, true);
   Common.ExecuteString("flatten all Y ", true, false, true);
} 
lDoc.CloseAndSave(lNewName);

Thank you Ed, that gave me a promising start, but I'm still having trouble. I've posted my revised code below. If I run as is, I get an eInvalidInput error. If I comment out the line with flatten, the command executes fine, saving a new copy of the file, but it does not zoom first. 

I must have missed something from the linked thread, so if you can help me figure it out I'd appreciate it!

Thanks!

[CommandMethod("SuperFlatten")]
        public static void SuperFlatten()
        {
            var lFileName = "C:\\Users\\KDhyne\\Desktop\\DWG Testing\\4821410SA2.dwg";
            var lNewName = $"C:\\Users\\KDhyne\\Desktop\\DWG Testing\\2D\\{Path.GetFileNameWithoutExtension(lFileName)}_TOP.dwg";
            var lDoc = ACAD.DocumentManager.Open(lFileName, false);

            using (DocumentLock docLock = lDoc.LockDocument())
            {
                lDoc.Editor.Command("_ZOOM", "All");
                lDoc.Editor.Command("FLATTEN", "ALL", "Y");

            }

            lDoc.Database.SaveAs(lNewName, Autodesk.AutoCAD.DatabaseServices.DwgVersion.Current);
            lDoc.CloseAndDiscard();
        }

See comments in red.

Hi,

First, FLATTEN is not a command, it's an Express Tools LISP function  and cannot be called with the Editor.Command() method.

As said in the topic linked by @ed57gmc, Editor.Command() can only be called in the Document context, so it cannot be used in a command decored with CommandFlags.Session.

In my opinion, if you want to batch process files using AutoCAD commands and AutoLISP function, you should try with accoreconsole and/or some batch scripting application as ScriptPro.

Thank you very much Gilles, I was able to create a very simple script and use ScriptPro to process an entire folder of drawings!

Can you provide a code sample that runs Express Tools' "Flatten" and receives an object as an input parameter?
