DEM pickPoint using 2 points on same vertical

[Paulo]

Hello,

I am trying to do a DEM pickPôint with 2 points pt1 and pt2 with pt2 1 m higher than pt1 and same X Y.

The DEM is about 3 m higher than pt2. However pickPoint returns None....

Any idea why this is so?

Hello Paul,

We'll check, why it doesn't work for identical XY values, but I think you can add 0.000000001 to either coordinate in any of two points to make it work.

Thank you Alexey,

however adding this small value to one of the points, still DEM.pickPoint doesn't give a result...

Hello Paul,

Can you check the result on your project, when at least origin point is above the DEM?

Hi Alexey,

I tested again with 2 points over and below DEM on vertical and pickPoint gives nan Vector..
