Property and Quantity Sets as Attributes
FME will read property and quantity set values associated with IFC elements as attributes on the features that represent those elements. These attributes will take the form <PropertySetName>.<PropertyName> and <QuantitySetName>.<QuantityName>, respectively.
In the case of duplicate property names belonging to the same property set, FME will create a list attribute where each entry is one value of the property.
FME will add additional type specifiers to the properties it reads. For example a, property set Pset_BuildingCommon containing a property IFCPROPERTYSINGLEVALUE('BuildingID',$,IFCIDENTIFIER('1234'),$) will be represented by the following attributes in FME:
- Pset_ProjectCommon.BuildingId.NominalValue = 1234
- Pset_ProjectCommon.BuildingId.NominalValue.DataType = IfcIdentifier
- Pset_ProjectCommon.BuildingId.PropertyType = IfcPropertySingleValue
