Hi,

It seems like you want to run before you know how to walk.

You should learn the basics of the AutoCAD .NET API with simpler tasks.

for example, concerning selection sets, you should read this topic and more accurately about selection sets this one.

I want to list the mores and names of the blocks in the drawing so I know the autocad selection sessions and filtering processes.

Did you try your code to select blocks?

It seems to me it can't work. You confuse block name and block file name (with .dwg extension) which won't work in a selection filter, and you selection filter contains many superfluous expressions.

You can try the following code.

        [CommandMethod("BLKCNT")]
        public static void Test()
        {
            var doc = Application.DocumentManager.MdiActiveDocument;
            var db = doc.Database;
            var ed = doc.Editor;

            var filter = new SelectionFilter(new[] {
                new TypedValue(0, "INSERT"),
                new TypedValue(2, "name1,name2,name3") });
            var psr = ed.GetSelection(filter);
            if (psr.Status != PromptStatus.OK)
                return;

                var ppr = ed.GetPoint("\nSpecify the table insertion point: ");
                if (ppr.Status != PromptStatus.OK)
                    return;

            using (var tr = db.TransactionManager.StartTransaction())
            {
                var blocks = psr.Value
                    .Cast<SelectedObject>()
                    .Select(so => (BlockReference)tr.GetObject(so.ObjectId, OpenMode.ForRead))
                    .GroupBy(br => br.Name)
                    .ToDictionary(gr => gr.Key, gr => gr.ToArray());
                double rowHeight = 9.0;
                double colWidth = 50.0;
                var table = new Table();
                table.TableStyle = db.Tablestyle;
                table.Cells[0, -1].Style = "_TITLE";
                table.Columns[0].Width = colWidth;
                table.InsertRows(1, rowHeight, blocks.Count + 1);
                table.InsertColumns(1, colWidth, 2);
                table.Cells[0, 0].Value = "BLOCK DATA";
                table.Cells[1, 0].Value = "PREVIEW";
                table.Cells[1, 1].Value = "BLOCK NAME";
                table.Cells[1, 2].Value = "COUNT";
                int row = 2;
                foreach (var entry in blocks)
                {
                    table.Cells[row, 0].BlockTableRecordId = entry.Value[0].BlockTableRecord;
                    table.Cells[row, 1].Value = entry.Key;
                    table.Cells[row, 2].Value = entry.Value.Length;
                    row++;
                }
                table.Position = ppr.Value;
                table.TransformBy(ed.CurrentUserCoordinateSystem);
                var cSpace = (BlockTableRecord)tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite);
                cSpace.AppendEntity(table);
                tr.AddNewlyCreatedDBObject(table, true);
                tr.Commit();
            }
        }

Thanks for this. Im having an error in

var blocks = psr.Value
.Cast<SelectedObject>()
.Select(so => (BlockReference)tr.GetObject(so.ObjectId, OpenMode.ForRead))
.GroupBy(br => br.Name)
.ToDictionary(gr => gr.Key, gr => gr.ToArray());

Error 4 'Autodesk.AutoCAD.EditorInput.SelectionSet' does not contain a definition for 'Cast' and no extension method 'Cast' accepting a first argument of type 'Autodesk.AutoCAD.EditorInput.SelectionSet' could be found (are you missing a using directive or an assembly reference?)

Hi,

Try like this:

var blocks = psr.Value.GetObjectIds() .Select(id => (BlockReference)tr.GetObject(id, OpenMode.ForRead)) .GroupBy(br => br.Name) .ToDictionary(gr => gr.Key, gr => gr.ToArray());

Does your drawing contains blocks named name1 or name2 or name3? because the selection filter only search for these block names.

var filter = new SelectionFilter(new[] { new TypedValue(0, "INSERT"), new TypedValue(2, "name1,name2,name3") });

You should not just copy/paste codes you do not understand, this is the worst way to learn.

Hi @_gile

what is the difference between these filters

TypedValue(2, "name1,name2,name3")

var filter = new SelectionFilter(new[] { new TypedValue(0, "INSERT"), new TypedValue(-4, "<or"), new TypedValue(2, "name1"), new TypedValue(2, "name2"), new TypedValue(2, "name3"), new TypedValue(-4, "or>"), });

var filter = new SelectionFilter(new[] { new TypedValue(-4, "<and"), new TypedValue(0, "INSERT"), new TypedValue(-4, "<or"), new TypedValue(2, "name1"), new TypedValue(2, "name2"), new TypedValue(2, "name3"), new TypedValue(-4, "or>"), new TypedValue(-4, "and>"), });

They work the same way, some are just most verbose.
