Look at ValiArchitect's InstantTerrain and their other tools.

True, the stamp tool does not often create a realistic grading for buildings and other applications. You really have to know something about grading and model it yourself, if you want something realistic. There are videos by professional LA regarding their methods.https://sketchucation.com/ flagle

Good terrain manipulating tools include Artisan and VertexTools.

Could you maybe provide me with one link to "professional LA videos"? The Trimble video that I saw was depressing.
