Do you mean using the EditWorld cheat? You can remove lots with the Remove tool if the cheat is enabled by clicking anywhere on the lot.
Viewing post in Delete Lots
Hi! I wanted to make a custom world and this doesn't work for me unfortunately. The lots are completely empty (devoid of households, objects, anything) and I have"EditWorld" plus"IgnorePlacementRules"activated. I then select the Remove tool (I tried both the button and "quick remove" by pressing Ctrl) and then I tried clicking on both the active lot and other surrounding lots, but nothing happens.
Any help is appreciated!
Hi! This feature changed a long time ago. However, you can now find all the information you need for making a custom map on the docs site. Good luck!
Hi! We recently updated the docs to include this information more clearly. Thanks for letting us know!
