Martin______________________________________________ Thanks Martin, that seems logical now that I think of it that way. I have been of the habit of only specifying the cs once for any cave system, and Therion seems to assume that the sub-surveys will be the same as the top level survey cs. It is reasonable that one might want a layout presented in a different cs. I tried it (conservatively with one cs) and it works fine! Thanks Bruce
