@mehdi-guida I'm not sure if this is the best way to do it, but it seems to work on the Mtext objects I've tested with.

[CommandMethod("ShowMtextAnnoScale")] public void showmtextscale() { var doc = Application.DocumentManager.MdiActiveDocument; var ed = doc.Editor; var db = doc.Database; var entPrompt = new PromptEntityOptions("\nSelect an Mtext:"); entPrompt.SetRejectMessage("...not an Mtext object."); entPrompt.AddAllowedClass(typeof(MText), true); var entSel = ed.GetEntity(entPrompt); if (entSel.Status != PromptStatus.OK) return; ObjectContextManager ocm = db.ObjectContextManager; ObjectContextCollection occ = ocm.GetContextCollection("ACDB_ANNOTATIONSCALES"); using (Transaction tr = db.TransactionManager.StartTransaction()) { var mtext = (MText)tr.GetObject(entSel.ObjectId, OpenMode.ForRead); if(mtext.Annotative == AnnotativeStates.False) { ed.WriteMessage("\nSelected Mtext not annotative!"); return; } //the ObjectContexts class is in the Autodesk.AutoCAD.Internal namespace var oContexts = ObjectContexts.GetContexts(mtext, occ.Name); var scale = ""; foreach( var context in oContexts ) { if (context.Name == occ.CurrentContext.Name) { scale = occ.CurrentContext.Name; break; } scale = oContexts[0].Name; } ed.WriteMessage("\nSelected Mtext has the current annoscale of {0}.", scale); } }

Thats weird. What year software are you using?

Do you have a reference to the Acmgd.dll?

No, but when I add Acmgd.dll the Acdbmgd.dll automatically will be removed and I get a lot of error.

That does seem strange. Again, what year AutoCAD are you referencing?

Here are the references that I use and I do not have any issues.
