An arch in The Sims 2

An arch or archway is an architectural object in The Sims games. They have been present in all games, but were not placed in a separate sub-category until The Sims 2.

Arches function like doors, except that they do not have a panel which can be opened and closed. In effect, an arch is a door that is always open. In fact, many arches are simply door frames without the doors. This is particularly true in The Sims 2, where almost all Maxis-made doors have a corresponding arch.

Despite appearances, an arch appears to work as well as a door for separating one room from another, or separating the indoors from the outdoors.
