4.8.2.7.3 Body Tessellation Geometry

The Body Tessellation Geometry is the representation of the 3D shape of a product by tessellated surface models.

The following attribute values for the IfcShapeRepresentation holding this geometric representation shall be used:

• IfcShapeRepresentation.RepresentationIdentifier = 'Body'
• IfcShapeRepresentation.RepresentationType = 'Tessellation'
• IfcShapeRepresentation.Items = IfcTessellateditem

Figure 76 illustrates an instance diagram.

Figure 76 — Body Tessellation Geometry

Examples:

• Tessellated item
• Beam straight I-shape tessellated
• Beam curved I-shape tessellated
• Column straight rectangle tessellation
• Slab tessellated unique vertices
• Tessellation with individual colors
