Yes you can do a flyby in ADT. Use the cameras to do this. It's the same with MAX, but much more cumbersome. Max is what you really want to use since you can create avi and mov files in max where ADT, I don't recall seeing that ability. Also, it's easier to do lighting and cameras in MAX. Oh, and that VIZ Render thing in ADT is garbage. It's only for materials. All the lights and cameras are still like the standard Autocad objects. Using max allows you to see light and shadow before rendering it, although it's still not exact. Then, be careful with radiosity solutions. Those can be tricky. Have fun. I think it is.
