Hello guys,
I want a function to view the terrain shape and measure its height. How can I draw a line from 2 points on the surface of the model.
Can anyone give me some directions. Any information is precious to me.
Thanks.

Thank you for your response. But what I want is a line connecting 2 points and lying on the surface of the object, not a line segment representing the distance of those 2 points.
Like that:
One of solution is using geometry intersection. Line like thin box.

@vacsHoai did any of the suggestions here work for you? I am trying to do the same thing (draw a surface line and do a measurement), but with a more complex mesh. Thanks!
