Identifier of the type to assign to this subelement.


In rare cases, applying a change in type will result in a new element being created. The only active examples of this are when:
  • Applying a normal wall type to a curtain panel.
  • Converting such a wall back to a curtain panel.
  • Applying a new type to a railing subelement.
In this situation this subelement object will be redirected to the new element.
