I am a new user trying to show a large 6'x 24' planter box with 12" thick walls attached to the corner of our NYC building. I used the Terrain>Garden Bed feature to raise the terrain elevation inside the box to 26" above the sidewalk and have been able to place plants as I wanted. I created a 28" high Terrain Wall around this and surfaced it with sandstone using Terrain path. My problem is the 3D view shows the walls (which are a horizontal 28" on both sides) angling down at each end to almost ground level. At the corner where the two walls meet they also form an angle rather than a vertical face.
Perhaps Terrain Wall is not the right way to do this? Any help would be appreciated. I am using HD Suite for this so I can show building management the look of this bed in front of the windows and brick and sandstone walls, and to also show the residents in the ground floor apartment the view of the garden bed out of their window. I have two more larger raised beds to design that can be viewed from lobby picture windows so it would be great to be able to work this out.
