public static void UpdateCustomConnectionType(
	StructuralConnectionHandler structuralConnectionHandler,

	IList<Reference> removeReferences
)

Parameters

structuralConnectionHandler  StructuralConnectionHandler
The existing StructuralConnectionHandler having custom StructuralConnectionHandlerType which is about to be modified.
addReferences  IListReference
References to elements or subelements which are to be used to modify custom StructuralConnectionHandlerType by adding them.
removeReferences  IListReference
References to subelements of input StructuralConnectionHandler which are to be used to modify custom StructuralConnectionHandlerType by removing them.
Exceptions
ExceptionCondition
ArgumentException Input StructuralConnectionHandler must have custom type. -or- All the input Elements should be of the following structural categories: framings, columns, profiles, plates, bolts, anchors, shear studs, welds or structural connections. -or- Total number of different input elements of input StructuralConnectionHandlers must be lower or equal to 3. -or- All the input references must belong to input StructuralConnectionHandler. After modification of StructuralConnectionHandlerType there must remain at least one subelement of structural connections category in StructuralConnectionHandler.
ArgumentNullException A non-optional argument was null
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.
