How to add a door to a wall? about xbimessentials HOT 8 CLOSED

I'm sorry but this is beyond the level of support I can provide here. I can only recommend you to create very basic example (simple wall with an empty opening, wall with very simple window) in some authoring tool (Revit, Archicad, Tekla etc.) and study the structure of the file. Make sure your placements and their relations are correct.

You need to create opening object and build the hierarchy. See this.

I understood the relationship mechanism. Thank you very much.

I am also trying to add a window to a wall. According to xBIM Xplorer the semantic hierarchy is correct already.
I created an IfcOpeningStandardCase, IfcRelVoidsElement, IfcRelFillsElement and the relations.

I am still struggling with the geometry for a few days now...
Could you post a code snippet how you put a window/door in the middle of a wall?

Thanks a lot.

Thanks for your fast response. I managed to add an IfcWall + IfcOpening + IfcWindow to an existing IFC-file (IFC4).
Unfortunately this didn't work for an IFC2x3, although I implemented the "Fast upgrade track to IFC version agnostic solution". I had to repeat the same process (with IFC2x3 libraries) in order to get it work.

Is there a better approach for an IFC-Schema independent solution?

Thanks a lot.

Please, take the time to read the more detailed description which includes use of Xbim.Ifc4.Interfaces.Create helper object.

Sorry its me again. Of course I did. I created a Create Instance in CreateWall() in the "Create Proper Wall in 3D" Example and created all non-abstract entities via create.Wall(), create.CartesianPoint(), and so on. Thus of course some functions are not working anymore. For instance IfcCartesianPoint.SetXYZ()

Furthermore according to the changes from IfcWall to IIFcWall I can not add easily the wall to a BuildingStorey anymore.

You can, if you only work with IFC4 interfaces and don't mix concrete types in. But yes, if has certain limitations.
