Colour by date can sometimes be a useful tool for viewing 3d files in Aven, especially when viewing to different datasets for the same passage in parallel.
However, 3d files generated by Therion, as opposed to Survex, don't seem to support this feature. There does not seem to be a similar feature in Lox. Might it be possible to implement this at some point? Graham --- graham.mullan at coly.org.uk 0117 9502556 or 07887 637064 (or try 0844 2327803)
