You have to see it to believe it. This guy was at the International Log Builders Conference last month (I was there teaching Sketchup to the roundies). He feeds each log through a scanner, that maps the entire surface of the log in 3D. Then, using your cad system, you stack these log objects created by scanning, and get the whole building looking the way you want. Then you feed the logs into the machine, and it cuts the scribe channel! He showed a video at the conference, but I don't see it posted on his web site. CB.
