Buildings or objects that are no longer needed, or have been built in the wrong
place, can be demolished. To demolish a building, click the pickaxe
icon. Next move the cursor to the building, road, or plant you wish to
demolish and click the left mouse button. The building or object will immediately
disappear from the screen. If you want to clear an entire area, hold the left mouse
button down and draw a frame around the area you want to clear. All the selected
objects inside the frame disappear.
You can use this, for example, to clear land for a farm even after you have
already built the farmhouse. In this case only the plants around the farmhouse will
be removed, while the farmhouse remains untouched. Careful: the "demolish" function
is final. If you mistakenly tear down the wrong building, you will have to rebuild
it using standard methods and resources.
