Hi,

I have a question about the 'Fraction' field. Can it be set for all relation types (One of: HasMaterial, HasReference, IsEqualTo, IsSynonymOf, IsParentOf, IsChildOf, HasPart) or only for some?

Thanks.

Reading the description

Optional provision of a fraction of the total amount (e.g. volume or weight) that applies to the Classification owning the relations. The sum of Fractions per classification/relationtype must be 1. Similar to Fraction in IfcMaterialConstituent

it would appear to apply to HasMaterial only.

It applies to all relation types: "The sum of Fractions per classification/relationtype must be 1".
The reference to IfcMaterialConstituent is just an example.

So @Baars-IT what is the meaning of Fraction for relations other than HasMaterial?
