I think John is trying to import the mesh into Archicad and not the point cloud. Which makes sense, because point clouds are not that useful when it comes to producing drawings.
John, you can import meshes into Archicad, for example in 3ds format. I've previously done this with a landscape mesh, including the texture. Importing the mesh was easy, however getting the texture to align to the object was a huge pain. It also heavily slowed down the viewport. You might be able to use hotlinks to attach the file and maybe this will make the process easier.
