I'm having an issue with an IFC export from Tekla 19 to ArchiCad 19. The problem seems to be with the Haunch. It's a connection between a column and a beam. Both HE-B 500. The whole model in ArchiCad shows up, except for the haunch itself. Even the bolts are there, but in the haunch area it cuts through the whole beam and where the beam should show up it's totally empty.
