I do this manually as I'm typically the one who also takes the spot elevation shots when I measure out a job. Tig did discuss a LISP routine to convert to a point cloud which could then be converted to terrain. There's a similar discussion here viewtopic.php?f=15&t=14409&st=0&sk=t&sd=a&hilit=cloud The website with the convertor is not in existence any more and I wondered if there has been a plug in produced since then. This isn't a 3d point cloud so can't use cloud.rb as the points are all on the same plane.
