how do u delete walls on sims
In build mode, just click on the wall tool as if you're gonna build a wall, but instead hold down control as you &build& over the wall you want to delete. It will delete the wall instead of build one.
click the ctrl key while draggin with the mouse.
hold down control then a bulldozer icon will show up instead of the other picture with wall building tool. then click on the walls that you want to delete while holding down control. =) Have fun building!
