I actually have two questions. Is there a cheat for creating a much larger lot? Also, I can't seem to be able to delete the roads, or for that matter, create new ones. Any ideas? I tried the boolprop code, but it didn't work. Any help would be greatly appreciated!
Experiments with lots larger than I think 65x65 tiles (lotsixed tiles) have shown the game cannot save the file without crashing. So that would be out.
Deleting the roads from the lot itself can be done using the "boolProp locktiles false" cheat. If you want to get rid of the neighborhood road by your lot, if you have the original terrain (before it was made into a new hood) you can reedit it in SC4 and remove that road and I believe somewhere on MATY is instructions for how to reintroduce that terrain over your existing hood.
Or if you can wait for the new Lot Adjuster, that will allow you to move your lot away from the road.
