Lot assignment

Lot assignments control the number and types of Sims that visit a lot in The Sims 3 and its expansion packs. They can also cause moodlets to appear, boosting moods or skill building. Every lot in the game has an assignment. Assignments can be set for a unique world using the Create a World tool, they are preset in premade neighborhoods, but can be changed using Edit Town. Rabbit holes also change lot assignments. Some assignments are locked for use in-game, or can only be used in certain sub-neighborhoods. Many lot types are hidden in-game, but can be unlocked by  which enables some Create a World and hidden lot types. Lot assignments were reintroduced in The Sims 4.

Map Tags
Map tags in The Sims 3 are clickable, interactive buttons that spring up from the birds-eye view when in Map View. Map tags can relate to a variety of lots and sims. Map tags also generate for opportunities and adventures. Community lot tags are a deep blue color. A lighter blue tag represents a player's selected sim's place of work (exception with professions and certain careers). Lighter, cyan colored tags usually represent a specified rabbit hole, specifically places a sim may work. A green tag represents the player's household he is currently playing. If there is a PlumbBob above the map tag, a player's selected sim is at that current location (for example if the sims is in the theatre it will show a plumbob above the theatre tag). Bright, vibrant tags represent opportunites involving opportunites, professions (see The Sims 3: Ambitions), or actions that are not particularlly related to game play such as Neighborhood Pet Adoption (see The Sims 3: Pets). Less bright orange tags represent another sims' dwelling. These map tags only appear when a player's selected sim has met a sim of the household. Red tags represent commercial areas such as schools, bistros, diners, subways (see The Sims 3: Late Night), jails, and grocery stores. Enabling the  cheat will make the map tags flash colorfully when viewed from the map view.
