Waypoint altidude and DEM in X/Y Diagram

Hi,

I have Touratech 3 and I'm using it to verify if there is a line of sight between 2 points. I'm using SRTM elevation files.

Basically, I create a route with 2 waypoints and I use the X/Y diagram feature to see the terrain profile between the points.

I have the "real" altitude for each of my waypoint. I can enter it manually in the watpoint Altitude field in the X-plorer. I was wondering if there is a way to use the X/Y diagram with the DEM activated and to have a waypoint represented with its altitude value from the Altitude field.

In other words, with the DEM activated in the X/Y diagram, can the Altitude value of a wapoint override the DEM value that is at that waypoint location?

Thanks!

Thanks for the quick answer...

As an example, if I had 2 telecommunication towers that are 20 meter above the ground, I would represent them with 2 waypoints that would have an altitude equal to the ground altitude + 20 meters. That way, I would be able to determine if the 2 towers could see eachother without any terrain obstruction...
