It's great that Archicad now supports point cloud import, however visualization capabilities are very limited. Working with non-colourized point clouds, one is presented with an indiscernible black blob of points. This is to be expected, but what is needed are some colour ramp filters that colourize the point cloud by elevation and by face/normals. Transparency, point size, and decimation display tools would also help tremendously when modelling.
It would also be nice if the point cloud had it's own dedicated clipping box controls, so that you could easily focus on small areas of the point cloud at a time without slicing the whole model. Finally, I'd like to see a range slider to control Z axis display (top and bottom), without having to open the object settings.
In the meantime, Revit and now Sketchup have much stronger point cloud support.
