Select a style, then drag the door to the spot you want it and release. Later, if you'd like to change doors or remodel, simply control-click to remove the door. Good for Sims who are just starting out. This lovely federal-style door is fitted with seven rows of three panes of glass. A vast array of windows are available for your Sim home.
Same rules apply.
Click to place, control-click to remodel. Windows help the Room rating by providing much-needed daytime light. Since the roof doesn't cost you anything, mess around with different looks until you find something that suits you. The roof is ultimately a minor concern, since it cannot be present to monitor Sim activity anyway. Grab something to drag by clicking on it once, then move it at will.
