Checking new data with Loch, I noticed that walls are just tube-like shaped.

I can see splayshots, but no way to use them to create correct walls.

When I mix new and old (with LRUD's) data I can see ONLY centerline and

splay shots on new ones, without any kind of walls.

Giorgio I too am just getting into paperless survey with the distoX. I understand that Loch does not yet produce passage walls from splay shots. The generic tubes you are getting are what you get when Loch thinks there is no LRUD data, so that the model at least looks a bit like a cave I guess. When you cannot see the splays, use Tools.Scene menu item, select centreline and tick splays, as below if you can see the enclosed pictures. You can make other 'scene' changes here as well. In the Loch screenshot below, the background passage has LRUD data (surveyed the paper way), and the foreground has only splay shots (paperless survey). Both passages have a plan drawing, and so the plan outline of the passages is mimicked in the Loch model. For the paperless survey the passage height is a generic value that Loch determines, because it can not use the splay shots yet (they can be seen poking out of the top of the passage). I presume that if this paperless survey thing 'takes off', then passage wall generation from splay shots will be developed. Regards Bruce
