Hello everyone, I am using IfcOpenShell in combination with pythonOCC and I am currently dealing with the entity IfcOpeningElement. If I get a shape of this entity, is there a way to find out to which building element (e. g. which wall) this opening element belongs to? In the IFC file, this information is stored inversely (IfcRelVoidsElement), thus I am not sure if this information can be accessed in IfcOpenShell. Thanks in advance Stefan

Hello everyone, I use IfcOpenShell in combination with pythonOCC and have a problem with the ifc file AC20-FZK-Haus.ifc and the wall elements in the first floor (Wand-Ext-OG-2 and Wand-Ext-OG-4). I get all the vertices in pythonOCC via TopExp_Explorer and for the point that is marked in the attached picture I get the coordinates (12.00010005, 10, 3.2) instead of (12, 10, 3.2). My problem occurs when i want to recreate the front faces of the coordinates i got via TopExp_Explorer: They are not built...
