Adding a View (viewTableRecord) to Paper Space Layout

MarkSanchezSPEC — Wed, 16 Jan 2013 21:15:54 GMT

I have used the following code in a small app to create named views: LINK_TO_Autodesk_Help_Topic

HOWEVER...A user of mine tried running the command while in a paper space layout. It appears the view still gets created but only within Model Space.

The help DOES SAY that "a default model space view is created", but how would I specify that I want the view to be created within the "current" layout, either Model or Paper space?

I tried setting the .OwnerID property of the ViewTableRecord to "doc.CurrentSpaceID" but that did not work - no error either.

See article here

Here is a code very quickly translated on C#:

        [CommandMethod("VW")]
        public void tryCreateViewPort()
        {
            // Only works in paperspace
            Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
            Editor ed = doc.Editor;
            Database db = doc.Database;
            try
            {
                using (Transaction tr = db.TransactionManager.StartTransaction())
                {
                    ObjectId mCurViewportId = ed.ActiveViewportId; 

                    if (mCurViewportId == ObjectId.Null)
                    {
                        ed.WriteMessage("\nCommand only works in paperspace.");

                        return;

                    }

                    Viewport pCurViewport = tr.GetObject(mCurViewportId, OpenMode.ForRead) as Viewport;

                    if (pCurViewport == null)
                    {

                        ed.WriteMessage("\nCannot get active viewport.");

                        return;

                    }

                    if (pCurViewport.Number != 1)
                    {

                        ed.WriteMessage("\nCommand only works in paperspace.");

                        return;

                    }

                    // Ask for the position

                    Point3d pt1; Point3d pt2;

                    pt1 = ed.GetPoint("\nSelect first corner: ").Value;
             
                    pt2 = ed.GetCorner("\nSelect second corner: ", pt1).Value;
       
                    // Ask for the view to use

                    string mViewName;

                    mViewName = ed.GetString("\nEnter name of view to use: ").StringResult;
                
                    // Create new viewport

I really appreciate you taking the time to reply but...

Your post and the link refer to a paper space "Viewport" like you do manually with the "MVIEW" command. What I needed to do was create a "View" in paper space like you do manually with the "VIEW" command.

ViewTableRecord.IsPaperspaceView = true can help you

This is the same in my code:

pViewTR.IsPaperspaceView = true;

That was easy!

Thank you both Hallex and Alexander!
