Hi. When I import an IFC arhitectural model (made in Archicad), then some of the walls etc are missing (see the picture on right side). When I just open the IFC file in Solibri (an IFC viewer) just to have a look on it, then everything seems to be correctly displayed (see the picture on left side). What could cause the problem??? (I had similar problem actually before also with another project). I use Vectorworks Landmark 2020 and an Imac Pro. Thank you!
