General

Split data into entity models
  • If the attribute IfcEntity exists, Models will be created based on entity type.
Presentation layer as model
  • If the IfcPresentationLayer exists, Model names will be based on the Presentation Layer name.
  • The Presentation Layer takes precedence over ‘Split data into entity models’.
  • Any data not part of a PresentationLayer will be placed in the Entity Model or the Prefix*Model.
