:*In LoD1 a solid directly contains the bounding geometry ('''Figure A''')
:*In LoD1 a solid directly contains the bounding geometry ('''Figure A''')
:*In LoD2 and LoD3 a solid contains external references (Xlinks) to the bounding geometry ([[#Wall Surface|wall surfaces]], [[#Roof Surface|roof surfaces]], [[#Ground Surface|ground surfaces]], [[#Outer Ceiling Surface|outer ceiling surfaces]], [[#Äußere_Bodenflächen|outer bottom surfaces]] and [[#Closure Surface|closure surfaces]] as well as [[#Doors|doors]] and [[#Windows|windows]]). '''In real nonexistent surfaces''' are modeled as closure surfaces ('''Figure B''').

'''In reality not existing surfaces''' are modeled as closure surfaces ('''Figure B''').
:*In LoD2 a solid contains external references (Xlinks) to the real bounding geometry. '''In real nonexistent surfaces''' are modeled as closure surfaces and assigned directly to the building part ('''Figure C''').
