How to set Dimensions to Annotative using C#.NET

jlobo2 — Tue, 16 Jul 2019 17:53:28 GMT

We have a template setup with a "_STANDARD" dimension that is Annotative.

When we plot through the C# code below, we access the dimension, and set that.

The properties are being set, except for the Annotation. Can you please suggest what am I missing?CodeResult

Try this sample code:

using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.EditorInput;

[assembly: CommandClass(typeof(DimChangeAnno.MyCommands))]

namespace DimChangeAnno
{

  public class MyCommands
  {
    [CommandMethod("ChgDimAnno")]
    public void ChgDimAnnoHandler()
    {
      Document doc = Application.DocumentManager.MdiActiveDocument;
      if (doc == null) return;
      Editor ed = doc.Editor;
      PromptEntityOptions prOpt = new PromptEntityOptions("\nSelect Dimension: ");
      prOpt.SetRejectMessage("\nIt is not Dimension!");
      prOpt.AddAllowedClass(typeof(Dimension), false);
      PromptEntityResult prRes = ed.GetEntity(prOpt);
      if (prRes.Status == PromptStatus.OK)
      {
        using (Transaction tr = doc.TransactionManager.StartTransaction())
        {
          Dimension dim = tr.GetObject(prRes.ObjectId, OpenMode.ForWrite) as Dimension;
          switch(dim.Annotative)
          {
            case AnnotativeStates.False:
              dim.Annotative = AnnotativeStates.True;
              ed.WriteMessage($"\nAnnotativeStates.False -> {dim.Annotative}");
              break;
            case AnnotativeStates.True:
              dim.Annotative = AnnotativeStates.False;
              ed.WriteMessage($"\nAnnotativeStates.True -> {dim.Annotative}");
              break;
            default:
              ed.WriteMessage("\nAnnotativeStates.NotApplicable");
              break;
          }
          tr.Commit();
        }
      }
    }
  }
}

@Alexander.Rivilis I am using a similar code to change the annotative property. But whenever I use it, the dimensions do not show up in the drawing. I am plotting other block attributes as well.

The code, I am using is below:

            using (Transaction acTrans = theDb.TransactionManager.StartTransaction())
            {
                pBlockTbl = acTrans.GetObject(theDb.BlockTableId, OpenMode.ForWrite) as BlockTable;
                pModelSpaceTblRcd = acTrans.GetObject(pBlockTbl[BlockTableRecord.ModelSpace], OpenMode.ForWrite) as BlockTableRecord;
                //pBlockTbl.Dispose();           

                // Prepare dimension
                string tempDimensionTextToPlot =  string.Format("{0:0.00}", (rightDist - leftDist));
                
                pDimension = new AlignedDimension(
                    new Point3d(leftDist, originElev, 0),
                    new Point3d(rightDist, originElev, 0),
                    new Point3d(leftDist + ((rightDist - leftDist) / 2), originElev + elevDeltaToDimLine, 0),
                    tempDimensionTextToPlot,
                    idDimensionStyleStandard);        

                //change
                pDimension.DimensionStyle = idDimensionStyleStandard;
                pDimension.LayerId = idLayerDimension;
                pDimension.Annotative =  AnnotativeStates.True;

                // Add dimension to database
                pModelSpaceTblRcd.AppendEntity(pDimension);
                acTrans.AddNewlyCreatedDBObject(pDimension, true);

                // Finished with this dimension
                //pDimension.Dispose();

                acTrans.Commit();
            }

[CommandMethod("CreateDimAnno")]
public void CreateDimAnno()
{
  Document doc = Application.DocumentManager.MdiActiveDocument;
  if (doc == null) return;
  Database db = doc.Database;
  Editor ed = doc.Editor;
  using (Transaction tr = doc.TransactionManager.StartTransaction())
  {
    BlockTableRecord curSpace = 
      tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite) as BlockTableRecord;
    Dimension dim = new AlignedDimension(
                new Point3d(0, 0, 0),
                new Point3d(100, 0, 0),
                new Point3d(50, 20, 0),
                "<>",
                db.Dimstyle);
    dim.SetDatabaseDefaults(db);
    curSpace.AppendEntity(dim);
    dim.Annotative = AnnotativeStates.True;
    try
    {
      dim.AddContext(db.Cannoscale);
    }
    catch { }
    tr.AddNewlyCreatedDBObject(dim, true);
    tr.Commit();
  }
}

@Alexander.Rivilis

That is simply awesome. That worked great.

How do I know, that I have to append it first and then change the property?

Is there a website or a course I can learn all these things from?

Annotation Scales reffer to Database. So you have first add it to Database, and after make it annotative.

Only samples on this forum, other forums and blogs can help you.
