IFC4 Design Transfer View

The IFC4 Reference View targets all work flows that are based on reference models. Read more:

 

General scope of the IFC4 Design Transfer View

The general scope defines the main functionalities of the IFC4 Design Transfer View as an overview. It includes a complete listing of the model elements and model element types that are included in the IFC4 Design Transfer View Model View Definition.

NOTE The Model elements are referred to as "Root Concepts" within the Model View Definition specification, being the individual root elements, that contain the attributes, geometric shapes, dynamic property sets and other semantic information that are combined and expressed as "Concepts". The common definition of a "Concept", that is applicable to many "Root Concepts" is called a "Concept Template".

The detailed scope of the IFC4 Design Transfer View is determined by the concept templates that are included. A detailed description of each concept template is provided by Chapter 4 "Fundamental concepts and assumptions" listed in the MVD specification delivery.

Model elements included in the IFC4 Design Transfer View

Model elements

All model elements, that are included in the IFC4 Reference View, are also included in the IFC4 Design Transfer View. The following additional model elements are added to enable basic parametric capabilities.

Standard-case entities are defined by material configuration at type definitions (either IfcMaterialLayerSet, IfcMaterialProfileSet, or IfcMaterialConstituentSet, which are applied to an axis path or footprint area. Material profiles define cross sections of materials that are swept along a curve. Material layers define thicknesses of materials that fill a bounded area.

Standard-case entities include the following:

EntityMaterialRepresentation
IfcSlabStandardCase IfcMaterialLayerSetUsage 'Footprint'
IfcPlateStandardCase IfcMaterialLayerSetUsage 'Footprint'
IfcWallStandardCase IfcMaterialLayerSetUsage 'Axis'
IfcColumnStandardCase IfcMaterialProfileSetUsage 'Axis'
IfcBeamStandardCase IfcMaterialProfileSetUsage 'Axis'
IfcMemberStandardCase IfcMaterialProfileSetUsage 'Axis'
IfcDoorStandardCase IfcMaterialConstituentSet 'Profile'
IfcWindowStandardCase IfcMaterialConstituentSet 'Profile'
IfcOpeningStandardCase IfcMaterialConstituentSet 'Profile'


Elemented-case entities are defined by compositions of elements, where each composed element is defined by material configuration at type definitions. Elemented-case entities include the following:

EntityComponents
IfcSlabElementedCase IfcBeamStandardCase (joists)
IfcPlateStandardCase (sheathing)
IfcWallElementedCase IfcMemberStandardCase (studs, track)
IfcPlateStandardCase (panels)
IfcBuildingElementPart (insulation)

 

Model element types

All model elements types, that are included in the IFC4 Reference View, are also included in the IFC4 Design Transfer View, no additional model element types are added.
