The approach I took with my first similar problem prob isn't the most
efficient, but it was a start which helped me get to grips (somewhat) with
DX.
I created two datasets, both had the same position data, one had the
terrain (altitude) as the Z value, the other had the temperature, so I
started with 2 text files:
X Y height
...
and
X Y temp
...
These I imported, built connections & exported as DX files.
To drape them, I used the following (from memory, drape is a macro rather
than standard module?) approach:
import import
(terrain) (values)

Having learned a little more since writing this, now I'd look at importing
the data as a single file & use Mark to flag the columns to use for the
two drape inputs.
Another reference you might find useful is the tutorial at
http://www.phys.ocean.dal.ca/docs/DX_tutorial.html
which whows this functionality pretty well.
