Contents: Two interlinked models (architectural and structural) of a same building
- Architectural.ifc: Created with ArchiCAD 13, original name "ArchiCAD-Tekla COL-ARCH_V01.ifc"
- Structural.ifc:    Created with Tekla Structures using the Object converter 
                     No further design actions have been done

The parts in Structural.ifc have a PropertySet with name 'Workflow' that has a property 'initial_GUID' 
whose value is the GUID of the corresponding part in the Architecture.ifc. 

For example:
  #692= IFCPROPERTYSINGLEVALUE('initial_GUID',$,IFCLABEL('3WyVnYyYD449SyF7NsGMcr'),$);
  #693= IFCPROPERTYSET('0U2hmy4h1CVw8dBM1ZwJyB',#5,'Workflow',$,(#692,#34,#35,#36,#37,#38,#39,#40,#41,#42,#43));

There is currently only one structural part for each architectural part. This will change when the design 
proceeds as many structural parts need to be split into several parts. This is not reflected in these datasets.
