Creating Socketweld connection in Plant3D

Hello,

I'm trying to create a assembly with .NET to draw all objects from a chosen spec. I started from Plant3D SDK which have a sample project. Autodesk ADN support is too slow to answer some basic questions since they have changed support platform recently. So, I hope someone can help me here. :smileywink:
After hours searching and trying to reach the main goal, I understood how connections between objects are done. The connector is based on End Type of objects. I'm not a meterial guy, so everything is much more difficult to me :smileysad:
At CreatePipeline (..\Plant SDK 2013\Samples\Piping\CreatePipeline) sample we have a class PipelineConnector which create connector. The main problem is only Buttweld connector code is available at CreatePart method in this class. I'm needing a piece of code where creation for others connector types such as Socketweld are shown.
Please, any help is very very appreciated.

the CreatePart code below:

public override void CreatePart()
        {
            Database db = AcadApp.DocumentManager.MdiActiveDocument.Database;
            ContentManager cm = ContentManager.GetContentManager();

            part.Position = InsertPoint;
            part.SlopeTolerance = 0.1;
            part.OffsetTolerance = 0.0;

            if (ConnTypeName.Equals("Gasket"))
            {
                // Gasket
                //
                //PartName = "Gasket";
                var spGPart = GetSpecPart("Gasket");
                PSPColl.Add(spGPart);

                var blockSubPart = new BlockSubPart();
                ObjectId Id = ObjectId.Null;
                try
                {
                    if (spGPart.PropValue("ContentGeometryParamDefinition") != null)
                        Id = cm.GetSymbol(spGPart, db);
                    blockSubPart.SymbolId = Id;
                }
                catch { }

                part.AddSubPart(blockSubPart);

                // BoltSet
                // 
                var spBPart = GetSpecPart("BoltSet");

                BoltSetSubPart boltsetSubPart = new BoltSetSubPart();
                boltsetSubPart.PartSizeProperties.NominalDiameter = NomDia;
                boltsetSubPart.Length = NomDia.Value * 2;
                part.AddSubPart(boltsetSubPart);                
                
                PSPColl.Add(spBPart);
            }
            else if (ConnTypeName.Equals("Buttweld"))
            {
                Project activeProject = PlantApp.CurrentProject.ProjectParts["Piping"];
                PartSizeProperties psprops = new NonSpecPart();
                psprops.Name = "Buttweld";
                psprops.NominalDiameter = NomDia;
                psprops.Type = "Buttweld";
                psprops.Spec = SpecName;

                Double dWeldGap = 0;
                String bWeldGap = String.Empty;
                activeProject.GetProjectVariable("USEWELDGAPS", out bWeldGap);
                if (String.Compare("TRUE", bWeldGap, true) == 0)
                {
                    String sWeldGap = String.Empty;
                    activeProject.GetProjectVariable("WELDGAPSIZE", out sWeldGap);
                    if (!String.IsNullOrEmpty(sWeldGap))
                    {
                        Double.TryParse(sWeldGap, out dWeldGap);
                    }
                }

                WeldSubPart weldSubPart = new WeldSubPart();
                weldSubPart.Width = dWeldGap;
                part.AddSubPart(weldSubPart);
                PSPColl.Add(psprops);
            }
            
            PartObject = part;
        }
