If you have Use Property Mappings checked in the Options group the plugin will use these definitions when creating IfcPropertySets and IfcQuantitySets for each IfcElement.

Please note!

When Use Class Mappings is not checked the plugin will only use definitions that are mapped with IfcElement, like Pset_Common and IfcElementQuantity in the image above.

When Use Class Mappings is checked the plugin will use different PropertySets and QuantitySet definitions for corresponding IfcElement based on Class Mappings

 

 

 

Property Mappings are defined by using 3 tab pages Mappings, PropertySets and QuantitySets.

 

Mappings tab is for setting a mapping between IfcElement and PropertySet and/or QuantitySet.

PropertySets tab is for mapping Navisworks properties with common IfcPropertySets recommended by BuildingSMART for each object type. Besides of using common PropertySets you can also define custom PropertySets

QuantitySets tab is for mapping Navisworks properties with common IfcQuantitySets recommended by BuildingSMART for each object type. Besides of using common QuantitySets you can also define custom QuantitySets
