Custom Autocad Map Dimension Feature

[schikh]

Hi,

I need dimensions objects (like we have in Autocad) to be added to my industry model and that custom feature would be  manipulated like the Dimension in Autocad. Could you give me to information on how to code such feature or even better c++ sample code doing similar things.

Thanks,

SChikh

maybe you can get started with a dimension jig?

Hi Fieldguy,

Your reply interesting, showing the Dimension Jig when editing my point feature is something I will need, do you have an Idea how to permanetly show the Dimension ? This is needed to show distances in an Industry Model map (like in a CAD drawing).

Thanks,

here's a link to another dimension jig - this dimension gets "appended" to the modelspace blocktablerecord.

if i get time later today i will modify norman's code to add the dimension tot the database.

I was hoping you would solve this yourself.  Below is my interpretation of Norman's Move() method.  If the jig status is OK, add the dimension to the current space.

 public void Move2()
 {
     if (!SelectEntity(out ObjectId entId, out Point3d basePt)) return;
     _entityId = entId;
     _basePoint = basePt;
     _prevPoint = basePt;
     _movingPoint = basePt;
     var offset = GetDimLineOffset(_entityId);
     var dimTextPt = GetMidOffsetPoint(_basePoint, _movingPoint, offset);

     try
     {
         _dim = new AlignedDimension(
             _basePoint,
             _movingPoint,
             dimTextPt,
             "0000",
             _dwg.Database.DimStyleTableId);

         using (var tran = _dwg.TransactionManager.StartTransaction())
         {
             _entity = (Entity)tran.GetObject(_entityId, OpenMode.ForWrite);

             var res = _ed.Drag(this);
             if (res.Status == PromptStatus.OK)
             {
                 var db = _dwg.Database;
                 var cspacebtr = (BlockTableRecord)tran.GetObject(db.CurrentSpaceId, OpenMode.ForWrite);
                 cspacebtr.AppendEntity(_dim);
                 tran.AddNewlyCreatedDBObject(_dim, true);
             }
             else
             {
                 _dim.Dispose();
             }
             tran.Commit();
         }
     }
     finally { }
     _ed.WriteMessage("\nDim added");
 }
