[Therion] more newb questions

At this point I have centre line data for two caves connected by fixed points. Thanks for the last tip about cs. No LRUD data is entered yet. I have not done any drawing of walls or passage detail yet. I am just trying to figure out the basics. I am trying to export a kml file with the two cave centrelines but I don’t know how to get a different colour for each cave. I’d like my plan and profile PDFs to have two colours as well. Rob Countess
