Bimserver 1.5.125 updated Installed Plugin Bundles. The IFC file is 30 mb.

Its probalby not an bug, but lack of knowledge from my side. I have a question;

An IFC file is build up of several IfcElementAssembly structures. Each assembly contains both IfcBeam and IfcBuildingElementProxy objects. I would like to query all objects related to an IfcElementAssembly with "Name" : "Floor-01" including decomposition. Ideally I would also like to include IfcBeam and IfcBuildingelementProxy objects with certain properties, but that is an option.

I tried several ways;
"type": {
"name": "IfcElement",
"includeAllSubTypes": true
This IfcElement gives all contained objects perfect on screen, when later including decomposition it hangs. On screen top message "getting model data" is not dissapearing and CPU load is after half an minute to zero.

Subtitute IfcElement for IfcElementAssembly gives nothing

query IfcElement and later same with IfcElementAssembly with specific Assembly Guids gives nothing
"type": {
"name": "IfcElement",
"includeAllSubTypes": true
"guids": [
"3aMi53puf4RhFYlgosHaU", >> this one is changed for an actual IfcElementAssembly member

Can you give me an direction for the right query?
