MauraInteriors

Hi everyone. This is my first project in Home Designer Pro. I created an entire outdoor deck with steps down to the lower level (will be a grass/concrete walkway). I did the entire deck design before adding terrain. I'm guessing that was a mistake? Now when I add a terrain perimeter it's way too high and cuts off the steps. I watched a few tutorials and tried making an elevation break and setting the terrain to -24" but it does nothing. Anyone know how I can fix this? Thank you.
