This is a depression for the foundation of a house to be built on a hillside. However, it’s not going to be cut like that, it will be smoothed out to create a level “platform”.
What’s the easiest way to smooth the edges of the surrounding terrain, without disturbing the flat footprint? I tried Vertex Tools, but it’s more manual & makes an ungodly mess if you select an edge wrong.
Is there something that can act like a bulldozer basically?
