As mentioned previously, the shoots and splays are not displayed based on their actual vertical position but are piled up from top to bottom of the data table. This lead to very awkward display of caves where underlaying galeries can to displayed as if the were above upper ones. If this issue can't easily be solved in Perspectives (as I understand CRP uses a 2D viewer to display 3D data), I believe it can be fixed in Plan view (and probably in Side view). The display process should include sorting the shoots and splays based on their Z position before display. This won't be perfect in all cases, but surely it will be much better than the current data table order. This shouldn't require any calculations, just sorting the data before display.
This should also be applied to kml export as it suffers the same issue.

great! looking forward to it! :)
