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.
