IfcRelNests parts only shown in Solibri hierarchy tree. IfcRelNests whole (parent) missing from tree

IfcRelNests parts only shown in Solibri hierarchy tree. IfcRelNests whole (parent) missing from tree.

Upon reading an ifc 4 or 4x3 file into Solibri, only the parts are shown under the Model Tree view. i.e. see image, part = ‘Flow Segement’

Whereas after running a patch using ifcopenshell, to convert IfcRelNests to IfcRelAggregate, the Model Tree view shows the Whole and part, i.e. see image, Whole = Assembly, part = Flow Segement.

Why aren’t both the Whole and parts shown when an IfcRelNest relationship between the whole and parts exists?
Any feedback on this item would be great, thanks in advance.

Thanks for this report. In the next release the model tree supports nesting and supports IFC4X3.
