Well, u can go to insert and look up "houses" then find a certain house that u want. But, u should also use tools and use "drag" so, u can put which way u want the house to face and drag it where u want the house to be.
Also for if u want to build ur own things u go to insert and bricks and click on a brick. there is a button 2 to the right of the drag button and u can make the brick as big, thin, etc. that u want it to be... |
