I wonder why it makes a difference to add the elevation filter for
you. I don't know what that filter does.
Even when I add elevation in 3.12.0 64-bit Windows version, it only
gives me RTdata, not Elevation, after the contour is
applied. Strangely, if I contour by RTData after applying Elevation
it also gives me only RTdata and not Elevation as a choice. Maybe it
is just skipping one of the entries in the contour?
Thanks,
Russ
