Hi, My first question : I am trying to draw an extended elevation for a small cave (before to go to the biggest one !). But, I do not arrive to produce any extended-elevation xvi file (The map/plan view is OK). The xvi file I got is systematically wrong : the stations are linked only 2 by 2, with no connections between each. Something must be wrong in my input files or in my understanding how to proceed extended- elevation, but I didn't find what, nor understood why... Does anyone have an idea ? My B3.th input file is : ************** encoding iso8859-2 survey B3 -title "B3" -entrance "B3" centerline -extend right date 2010.07.16 cs lat-long fix B3 46.101166833 6.78841683 2066.000000 # declination 0.00 degrees team "G.S.
