Hi,

I need to save the current view/zoom of the current document and then restore it.

How I can do this?

Thanks

Hi,

It seems to me the simplest way is to create a named view (ViewTableRecord).

        static void SaveCurrentView(Document doc, string viewName)
        {
            var db = doc.Database;
            var ed = doc.Editor;
            using (var tr = new OpenCloseTransaction())
            using (var currentView = ed.GetCurrentView())
            {
                var viewTable = (ViewTable)tr.GetObject(db.ViewTableId, OpenMode.ForRead);
                ViewTableRecord view;
                if (viewTable.Has(viewName))
                {
                    view = (ViewTableRecord)tr.GetObject(viewTable[viewName], OpenMode.ForWrite);
                }
                else
                {
                    viewTable.UpgradeOpen();
                    view = new ViewTableRecord();
                    viewTable.Add(view);
                    tr.AddNewlyCreatedDBObject(view, true);
                }
                view.CopyFrom(currentView);
                view.Name = viewName;
                tr.Commit();
            }
        }

        static void RestoreView(Document doc, string viewName)
        {
            var db = doc.Database;
            var ed = doc.Editor;
            using (var tr = new OpenCloseTransaction())
            {
                var viewTable = (ViewTable)tr.GetObject(db.ViewTableId, OpenMode.ForRead);
                ViewTableRecord view;
                if (viewTable.Has(viewName))
                {
                    view = (ViewTableRecord)tr.GetObject(viewTable[viewName], OpenMode.ForWrite);
                    ed.SetCurrentView(view);
                }
                tr.Commit();
            }
        }
