Bug on IfcWalls connections when exporting IFC from BlenderBIM to IFC.js

Hello, I have this bug on connections between walls. I joined them with the _Mitre _command of the BlenderBIM BIM Tool. I don't know if the bug comes from BlenderBIM or from the display by IFC.js

  • My guess is a bug in IFCJS, there are a few validation errors about the connectivity (which were fixed a few days ago) but those should not affect geometry. I also tested the model in other viewers which support tessellated openings like Solibri, Trimble Connect, Revit and they all work as expected. The half space solid definition also looks correct to me.

    I've reported it here: https://github.com/IFCjs/web-ifc/issues/240

    BTW, there is a new feature which allows you to apply those custom shaped voids as booleans, not openings. Currently you've defined them as openings, whereas booleans would be more semantically correct. You can add them as booleans the same way you can add half space planes as booleans.

  • Thanks Moult for the report, and the advise on voids. I just figured out how to do add one with the plus under IFC Booleans, but don't manage to edit it.

  • Correct, it's not yet possible to edit booleans (only add / remove), editing will come soon as a feature.
