My "export model -o ##NAME##.kml" exports work fine but "export map -o ##NAME##.kml" sometimes works perfectly but other times I get small pieces/part of a cave missing. I have checked for walls/pillars with the tick mark the wrong way round and all look OK. I notice that other people have had issues with this a while back and even noticed that Andrew stopped using kml output. In all cases the compile runs with no warnings and the pdf output is fine. Am I wasting my time, is there a better way to get similar results. Also on the "model" outputs is there a way to show just centreline and not the splays, I see this question has been asked before but I could not see an answer. I really quite like the kml outputs as you can get the evenings survey into Google earth before the first pints half way down whist sat in the pub afterwards -not always 100% positioned at this point but it still looks good - Nick.
