@kingpeterking, if there is I never heard of it. 🤔 Your boundary is in the game to mimic the property line in real life.
I want to use every inch possible, but your boundary for walls and fences is 1 grid square "in" around the perimeter. You can put other items on those perimeter squares, and even extend the footprint for a swing set, as an example, one grid square beyond the perimeter. However, anything that extends beyond the perimeter will vanish if you place that lot down after saving the lot to your library.
In real life you are not allowed to build all the way to the edge either and if you have neighbors I think they will object to having a swing taking some of their space.
lol My neighbors have the happy hive mind.....we all get along 🙂
This is what I meant. The swing set is still on the property, but the sims can swing over the perimeter. It works and is there in reload...but if I save this lot to the library and place the lot, that swing will vanish.
