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.
