In my office we use Archicad for moddeling. Then export eather IFC or FBX files that we import into Varjo Teleport software. There we bring in clients using two Oculus Rift S and two HTC Vive. In that way we can be one guide and three guests together. It's a fantastic way of making shore everyone understands your project.
There are simpler ways to get VR out of Archicad, but the feature that you can be in VR together is really important when communicating with clients.
