StructuralConnectionHandlerType.AddElementsToCustomConnection

Description:
Modifies StructuralConnectionHandlerType of input StructuralConnectionHandler by adding representors of input elements or subelements.

Remarks:
Elements or subelements added to a custom connection are deleted and transformed in subelements of the connection. They could be:

FamilyInstance (structural beams and columns).
StructuralConnectionHandler elements associated to the connection.
Specific steel connection elements (bolts, anchors, plates, etc). These connection elements will be of type element but with categories related to structural connections, for example:
- OST_StructConnectionWelds
- OST_StructConnectionHoles
- OST_StructConnectionModifiers
- OST_StructConnectionShearStuds
- OST_StructConnectionBolts
- OST_StructConnectionAnchors
- OST_StructConnectionPlates

You cannot add: elements connected by any connection handler, generic connections, holes and modifiers that are not on the connected elements.

StructuralConnectionHandler

structuralConnectionHandler

The existing StructuralConnectionHandler having custom StructuralConnectionHandlerType which is about to be modified.
IList<Reference>

references

References to elements or subelements which are to be used to modify custom StructuralConnectionHandlerType by adding their representors.

   // Select elements to add to connection.
   IList<Reference> refs = Utilities.Functions.SelectConnectionElementsCustom(activeDoc);

   if (refs.Count() <= 0)

      return Result.Failed;
   }

   // Start transaction
   trans.Start();
   // Adding the elements to the custom connection, using Revit's StructuralConnectionHandlerType class
   StructuralConnectionHandlerType.AddElementsToCustomConnection(conn, refs);
   // Commit the transaction
   ts = trans.Commit();
