Landscaping mounds

[DaveRegis]

I've got a flat lot with a landscape perimeter defined, and I'm trying to create landscaping mounds.   These need to be irregular-shaped and smoothly transition from the base terrain and raise to specified elevation.

 

Prior to HD-2027, there was a Terrain Modified menu selection that would let you define raised or lowered areas, but I don't see that anymore.   Is there a new way of doing this?

You could take a kidney shaped garden bed and convert it to an elevation region using the Convert Polyline tool (its on the Edit Toolbar when you have a qualifying object selected).

I  tried that, and it behaves like just creating a closed elevation spline.   It doesn't seem to have any affect at all regardless of the elevation I set; the area appears flat in 3D views.

You're right it does create an elevation spline. Elevation data needs to have contrasting information. if there is only one piece of elevation data it will always be flat. You'll need 2 pieces. If the majority of the lot is flat and you're jest adding a couple of mounds I would create a flat region that bends around the mounds at a lower elevation than that specified in the mounds.
