A breakthrough, thanks to Ben "Create point station, and name it with a station name within your survey (note that this is -name and not -id)." My simple misunderstanding and error was to try to make scrap survey station -id match survey centreline station numbers. Very counterintuitive, due to the interface not having a dedicated -name input box, and the object display area listing -id's but not -names. I guess that's why we help each other! At the risk of asking the same questions as recently answered posts. 1. Why does my centreline disappear beyond the extent of the scrap plotted? Whether I process just SurveyN.th or TheWholeCaveWithManySurveysINDEX.th I only get my first ever little scrap. I'd like to see it in context with my centreline with passage shading in the same output document. Loch seems to modify the passage with scraps while retaining all the passage with only centreline and LRUD data. I get the feeling I need to include the survey within the map command somehow, but no luck. 2. What is wrong with the following .th2 syntax created by the map editor interface? point 419.25 -243.0 label -orientation 0.0 Greenlink Entrance It triggers an error "-- unknown option - Greenlink" when I had hoped that it would plot the text on the drawing. If I comment out the line it works fine, just no labels! 3. I do like the way the .lox model follows the walls drawn on the scrap! Will it do the same if I create elevation scraps? Or only if I create extended elevation scraps? I have attached a complete self contained set of files that I using to experiment with these concepts. Regards Bruce
