What’s the easiest way to create windows in walls? I’ve created a large doctors surgery with multiple rooms. What’s the easiest way to put windows in?
The easiest way to create windows in walls is to build your room with building blocks such as the Cuboid. You can use the arrow size controls to easily adjust the width and length of a wall segment so that you can leave a gap to create a window.
