Try this code snip, change entity types in selection filter

on whatever you neeed:

     using System;
    using System.Collections.Generic;
    using System.Linq;
    using Autodesk.AutoCAD.ApplicationServices;
    using Autodesk.AutoCAD.DatabaseServices;
    using Autodesk.AutoCAD.EditorInput;
    using Autodesk.AutoCAD.Geometry;
    using Autodesk.AutoCAD.Runtime;
            public void ZoomWindow(Document doc, Point2d minpt, Point2d maxpt)
                ViewTableRecord view = new ViewTableRecord();
                view.CenterPoint = (minpt + (maxpt - minpt) / 2.0);
                view.Height = (maxpt.Y - minpt.Y);
                view.Width = (maxpt.X - minpt.X);
            public void testSelection()
                var doc = acApp.DocumentManager.MdiActiveDocument;
                var db = doc.Database;
                var ed = doc.Editor;
                PromptSelectionOptions pso = new PromptSelectionOptions();

                TypedValue[] filter = new TypedValue[] {
                    new TypedValue((int)DxfCode.LayoutName,Autodesk.AutoCAD.ApplicationServices.Application.GetSystemVariable("CTAB")),
                    new TypedValue((int)DxfCode.Operator,"<or"),
                    new TypedValue((int)DxfCode.Operator,"<and"),
                    new TypedValue(0, "TEXT,MTEXT"),
                    new TypedValue((int)DxfCode.TxtSize,3.0),
                    new TypedValue((int)DxfCode.Operator,"and>"),
                    new TypedValue((int)DxfCode.Operator,"<and"),
                    new TypedValue(0, "*LINE,CIRCLE,ARC,RAY,XLINE,MLINE,*LEADER,*DIM*,ETC"),
                    new TypedValue((int)DxfCode.LineWeight, 0.13),
                    new TypedValue((int)DxfCode.Operator,"and>"),
                    new TypedValue((int)DxfCode.Operator,"or>")};

                SelectionFilter sf = new SelectionFilter(filter);
                PromptSelectionResult res = ed.SelectAll(sf);

                if (res.Status != PromptStatus.OK)


                SelectionSet sset = res.Value;

                ed.WriteMessage("\nSelected {0} objects", sset.Count);

                using (Transaction tr = db.TransactionManager.StartTransaction())
                    BlockTableRecord btr = tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite) as BlockTableRecord;

                        ObjectId[] ids = sset.GetObjectIds();

                        if (ids.Length == 0) return;

                        var ents = from id in ids
                                   where id != null
                                   select tr.GetObject(id, OpenMode.ForRead);

                        var minx = (from n in ents
                                    where n != null
                                    select ((Entity)n).GeometricExtents.MinPoint[0]).Min();

                        var maxx = (from n in ents
                                    where n != null
                                    select ((Entity)n).GeometricExtents.MaxPoint[0]).Max();

                        var miny = (from n in ents
                                    where n != null
                                    select ((Entity)n).GeometricExtents.MinPoint[1]).Min();
                        var maxy = (from n in ents
                                    where n != null
                                    select ((Entity)n).GeometricExtents.MaxPoint[1]).Max();

                        ZoomWindow(doc, new Point2d(minx, miny), new Point2d(maxx, maxy));



                    catch (Autodesk.AutoCAD.Runtime.Exception ex)

i used ur code. but those 2 codes seem do not work

i used vb.net  .

i tried acTypValAr.SetValue(New TypedValue(DxfCode.LineWeight, LineWeight.LineWeight030), 0)

acTypValAr.SetValue(New TypedValue(DxfCode.LineWeight, 30, 0)

acTypValAr.SetValue(New TypedValue(DxfCode.LineWeight, 0.3, 0)

it also do not work :'(

new TypedValue((int)DxfCode.TxtSize,3.0),
new TypedValue((int)DxfCode.LineWeight, 0.13)
