A question about IfcPatch (ExtractElements) with Psets

1. A by avico on 25 Oct 2022, edited 27 Oct 2022 #

   Hi all,

   I'm testing IfcPatch to extract elements based on Pset Properties but without success.

   Te data I use (inside Blender Bim) in the IFC_Quality_Control -> IFC_Patch panel is:

   Recipes: ExtractElements

   IFC Path Imput IFC: The ifc file from I want data

   IFC Path Output IFC: The ifc file where I want save data

   query: .IfcElement[Pset_Name.Pset_Property = "My criteria"] (In my case .IfcElement[ACAT_Identificacio.ACAT-P3-Tipusnom = "GBB"]

   I use *= because I want all elements with "GBB" in that property, but this query doesn't work.

   I I use .IfcElement[Name *= "GBB"] as query work fine and get expected elements.

   The sintaxis for "Pset_Name.Pset_Properties" I use is based in previous test in IFC CSV tool and work fine. Looking the code, it seem csv analize Psets but ExtracElements.py not.

   Is there a way to extract elements according to pset with IfcPatch?

   I tested this and it works for me. Can you send me a sample model (dion@thinkmoult.com) with instructions and / or file a bug at https://github.com/ifcopenshell/ifcopenshell
