Deleting Wipeouts

[brianchapmandesign]

Is this correct?

namespace BCCDELWIPOUT
{
    public class DraftingTools
    {

        [CommandMethod("BCC:WOUT")]

        public static void BCCDELETEWIPOUT()
        {
            Document doc = Application.DocumentManager.MdiActiveDocument;
            Database db = doc.Database;
            Transaction tr = db.TransactionManager.StartTransaction();

            using (tr)
            {
                BlockTable bt = tr.GetObject(db.BlockTableId, OpenMode.ForRead) as BlockTable;
                foreach (ObjectId objId in bt)
                {
                    BlockTableRecord btr = objId.GetObject(OpenMode.ForRead) as BlockTableRecord;

                    foreach (ObjectId btrObjId in btr)
                    {
                        Entity ent = btrObjId.GetObject(OpenMode.ForRead) as Entity;
                        if (ent is Wipeout)
                        {
                            ent.UpgradeOpen();
                            {
                                ent.Erase();
                            }
                        }
                    }
                }
            }
            tr.Commit();
        }
    }
}

No,

Wipeout is nothing but closed lwpolyline

with number of verices more than 3 items,

with every bulged segments,

so you can check all these properties to make

sure if you select wipeout

Thanks again buddy!

Oleg! Are you sure??? Wipeout is Wipeout:

Thanks Alexander.  Don't think this was always exposed to the API, correct? Might be why the suggestion.  I'm using 2012 Civil 3D... think it will work...

I just don't know the right way to collect the Wipeouts... as you can see in my code...  I'm doing something wrong but not sure what.  One thing is I don't think I have to ent.UpgradeOpen, I think I can just ent.erase but I'm crashing so there must be something else wrong.

IMHO class Wipeout is exposed with AutoCAD .NET API since AutoCAD 2008.

Try replace code:

using (tr)
{
     //.......
}
tr.Commit();

with:

using (tr)
{
     //.......
     tr.Commit();
}

I knew that thanks

But why this way it's not working this way?

(ssget "_X" '(( 0 . "wipeout")))

Thanks Alexander you were correct! The placement of the TR was the problem.  Updated code below:

// delete wipeouts

namespace BCCDELWIPOUT
{
    public class DraftingTools
    {

        [CommandMethod("BCC:WOUT")]

        public static void BCCDELETEWIPOUT()
        {
            Document doc = Application.DocumentManager.MdiActiveDocument;
            Database db = doc.Database;
            Transaction tr = db.TransactionManager.StartTransaction();

            using (tr)
            {
                BlockTable bt = tr.GetObject(db.BlockTableId, OpenMode.ForWrite) as BlockTable;
                foreach (ObjectId objId in bt)
                {
                    BlockTableRecord btr = objId.GetObject(OpenMode.ForWrite) as BlockTableRecord;

                    foreach (ObjectId btrObjId in btr)
                    {
                        Entity ent = btrObjId.GetObject(OpenMode.ForWrite) as Entity;
                        if (ent is Wipeout)
                        {
                            ent.Erase();
                            
                        }
                    }
                } tr.Commit();
            }
        }
    }
}

Thanks! That was the way I did it in Lisp. I have decided to convert 10 years of lisp routines I've collected / created into C#, somewhat to learn, but also because I like the better performance with .net.  There is such little material about C# out there than there was .lsp it's considerably harder, but always enjoy a challenge 🙂

Thanks for the help Hallex! Always appreciated.

now i am doing the same work , convert 10-years of lisp to c#.
