Hi, How are you doing.
I want to ask about catchment delineation for Sewergems, When I add a specified terrain model with a specific boundary, When the road is for example curved, Triangles are added from outside that boundary by extrapolation and non required catchments areas are added to the delineated area, I do not want the terrain model to add elevations from outside my surface boundary.
For example, when I perform Trex for gravity elements, when some elements are outside the surface boundaries, Sometimes the Trex extrapolates the elevations for those nodes, I do not want that in catchments delineation.
Thank you very much.
