Hi Alexey,
I don't want to interfere with this request but I have a related feature request. For work in material stockpile estimates, we commonly have piles that abut other piles or banks or walls of some sort. The options in MS don't give us any options to deal with these problems.
Currently we move the project to Global mapper where we can specify the elevation value at each vertex in order to shape the base plane based upon conditions. In MS, the program already knows the calculated elevation value at each vertex, but there is no means to adjust or edit those values to modify the base plane.
The ability to do that in MS is my feature request.
Thank you!
Dave
