My terrain is flying crazy. The backyard is how I want it to look. The terrain should be level from the middle of the house up to the front of the terrain boundary. I have no terrain lines in the front of the house(opposite the deck) so why does it do this? What's an easy way to flatten it out (I already tried placing a terrain line every 5 or so feet and add more details but that just created huge "waves".
Also, how can I tell my deck to reframe?
