Hi, I want to plot both the centreline for the entire cave and passages in the scraps I have drawn. I can do one at a time but can't figure out how to plot both. In my thconfig file I have: symbol-show point station symbol-show group cave-centreline symbol-show point station-name debug station-names so when I don't have any scraps, I get the centreline and stations nicely plotted for the entire cave, which is proving very helpful with figuring out where to break loops for my extended elevation. However, as soon as I add in my scraps, which I've been doing by adding: input 107ee_ropeless.th2 input 107ee_china_new.th2 input 107ee_oldroute.th2 to my .th file I can only see the centreline (and walls, etc) for the scraps of drawn and not the rest of the cave. I'm sure it is possible to plot the scraps *and* the entire centreline. I'm sure I read it on a mailing list post when I was looking fro something else, but I can't rmanage to re-find it. Can anyone help? In case it makes a difference, I am plotted an extended elevation and reading in survex data as a 3d file. Thanks, Jenny
