[.NET C#] Xref DrawOrder eNoInternalSpace Error [Solved]
« on: February 16, 2024, 04:06:05 PM »
Hey guys

I'm trying to get all Xrefs in a specific order. The order is set through a list with all Xrefnames (order of list = draw order reversed).
It's getting the Ids of the Xrefs just fine, but on DrawOrderTable.MoveToBottom it gives the error eNoInternalSpace.
Does anyone have any idea why?

Thanks in advance

Code - C#: [Select]
  1.     [CommandMethod("XrefDrawOrder")]
  2.         public void XrefDrawOrder()
  3.         {
  4.             Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
  5.             Database db = doc.Database;
  6.             Editor ed = doc.Editor;
  7.  
  8.             List<string> xrefNames = new List<string>() {
  9.             "FS-X",
  10.             "BS-SN-x",
  11.             "BS-x_BS-G-x",
  12.             "EE-x",
  13.             "IB-x_SA-x",
  14.             "BS-AV-x",
  15.             "BS-AV-x_1"
  16.             };
  17.  
  18.             try
  19.             {
  20.                 using (Transaction tr = db.TransactionManager.StartTransaction())
  21.                 {
  22.                     XrefGraph xg = db.GetHostDwgXrefGraph(true);
  23.  
  24.                     GraphNode root = xg.RootNode;
  25.  
  26.                     List<XrefGraphNode> nodes = new List<XrefGraphNode>();
  27.  
  28.                     for(int i = 0; i < root.NumOut; i++)
  29.                     {
  30.                         XrefGraphNode child = root.Out(i) as XrefGraphNode;
  31.  
  32.                         if(child.XrefStatus == XrefStatus.Resolved)
  33.                         {
  34.                             nodes.Add(child);
  35.                         }
  36.                     }
  37.  
  38.                     foreach(string xrefName in xrefNames)
  39.                     {
  40.                         //get id of xref, this works.
  41.                         ObjectId id = nodes.Where(x => x.Database.Filename.Contains(xrefName)).FirstOrDefault().BlockTableRecordId;
  42.                         ObjectIdCollection entityIds = new ObjectIdCollection
  43.                         {
  44.                             id
  45.                         };                        
  46.  
  47.                         if (id != null)
  48.                         {
  49.                             BlockTable bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);
  50.                             BlockTableRecord modelSpace = (BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForRead);
  51.                             // Get the DrawOrderTable for ModelSpace
  52.                             DrawOrderTable dot = tr.GetObject(modelSpace.DrawOrderTableId, OpenMode.ForWrite) as DrawOrderTable;
  53.  
  54.                             //error here
  55.                             dot.MoveToBottom(entityIds);
  56.                         }
  57.                     }
  58.                     tr.Commit();
  59.                 }
  60.             }
  61.             catch (Autodesk.AutoCAD.Runtime.Exception e)
  62.             {
  63.                 ed.WriteMessage("\nError during shit: " + e.Message);
  64.             }
  65.             finally { db.Dispose(); }
  66.         }
  67.     }

I wonder if this is still an issue ?

You may need to go to AutoDesk for this question.
You'll need to provide a reproducible demo (code and drawing )

Thanks a lot for the second link! Dont know how you found that, cause I certainly didnt. =/

His solution was a bit convoluted but the takeaway was, that i had the wrong ObjectId. My working code looks like this now:


Code - C#: [Select]
  1. [CommandMethod("DrawOrder")]
  2.         public void DrawOrder()
  3.         {
  4.             Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
  5.             Database db = doc.Database;
  6.             Editor ed = doc.Editor;
  7.  
  8.             //Initialise list of xrefnames in order. Would be better to have it in a file and load it in or something instead of hardcoding.
  9.             //I use movetobottom so the first in this list will be on top of the others
  10.             List<string> xrefNames = new List<string>() {
  11.             "FS-X",
  12.             "BS-SN-x",
  13.             "BS-x_BS-G-x",
  14.             "EE-x",
  15.             "IB-x_SA-x",
  16.             "BS-AV-x",
  17.             "BS-AV-x_1"
  18.             };
  19.  
  20.  
  21.             // Build a selection filter looking for 'INSERT' objects (includes blocks and xrefs) from modelspace (DXF code 67 = 0)
  22.             TypedValue[] tvs = { new TypedValue(0, "INSERT"), new TypedValue(67, 0) };
  23.             SelectionFilter sf = new SelectionFilter(tvs);
  24.  
  25.             // Get objects matching the selection filter.
  26.             PromptSelectionResult psr = ed.SelectAll(sf);
  27.  
  28.             // Initialise Dictionary -> so we can search with linq. Dict cause you cant find the name in Entity, but in the blocktablerecord
  29.             Dictionary<string, Entity> xRefDict = new Dictionary<string, Entity>();
  30.  
  31.             try
  32.             {
  33.                 if (psr.Status == PromptStatus.OK)
  34.                 {
  35.                     // Get the object Ids from the selection.
  36.                     ObjectId[] ids = psr.Value.GetObjectIds();
  37.  
  38.                     using (Transaction tr = db.TransactionManager.StartTransaction())
  39.                     {
  40.                         //get the modelSpace
  41.                         BlockTable bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);
  42.                         BlockTableRecord modelSpace = (BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForRead);
  43.                         // Get the DrawOrderTable for ModelSpace
  44.                         DrawOrderTable dot = tr.GetObject(modelSpace.DrawOrderTableId, OpenMode.ForWrite) as DrawOrderTable;
  45.
