Build mode (The Sims 4)

Build mode is a main game mode in The Sims 4. Build mode is used to edit a lot, including architectural and construction changes, and the addition of objects. In other games in the series, purchasing, moving and manipulating objects is handled in a separate game mode, usually called buy mode, but in The Sims 4, these functions are included in build mode.

Build mode can be opened by clicking on the build mode icon in the game menu. It can also be accessed with two keyboard shortcuts; opens objects by room catalog (just as the same shortcut opens buy mode in other games), while  opens the build catalog.

Build mode tools


.

The following tools or menus (and their keyboard shortcuts, if applicable) are featured on the build mode tool menu:
 * Select tool - This tool allows players to pick up, move, delete, resize, and adjust objects and architectural elements on the lot.
 * Eyedropper tool - When pointed at a wall covering, floor covering, or most objects, the tool shows the name of what it is pointed at. Clicking on a wall or floor covering will switch to the appropriate area of build mode and select that covering so it can be applied. Clicking on an object will make an exact duplicate of it and will focus the catalog on that object.
 * Sledgehammer tool - This tool can quickly delete objects and architectural elements on a lot. Clicking on an object will delete the object (unless the object cannot be deleted). The tool can be clicked and dragged to select multiple objects or elements simultaneously.
 * Design tool - This tool is used to change an object's color or pattern. Using this tool does not incur any cost.
 * Undo and Redo ( and ) - When undo is used, the most recent change on the lot will be reversed. If an action is undone, redo will reverse the undo. Only changes made in the current session of Build Mode can be undone or redone; once play is switched to Live Mode, or the lot is exited, those actions cannot be undone or redone.
 * Lot info panel - Clicking this icon will open the lot info panel, which has several additional functions.
 * Save to My Library - Clicking this tool will save the active lot into the player's library.
 * Move Lot and House - Clicking this tool allows
 * Change time of day - Clicking this toggles between morning, afternoon, evening, and night on the lot, while in build mode. Changing time of day does not affect the actual time on the lot, which will revert as soon as the player exits build mode.

Lot info panel
The lot info panel gives information about the status and value of the active lot. It also allows players to change the lots assignment. The following information and tools are available on the lot info panel:
 * Lot name - The name of the lot is given at the top of the panel, near the center. The lot name can be changed by the player by clicking on the existing name.
 * Change venue - This tool allows players to adjust the lot assignment. This tool is unavailable if the lot is already owned by a Sim.
 * Lot progress - Clicking the lot progress icon shows the objects needed for a particular venue to be completed, and the number of required objects present on the lot. Each venue has different object requirements in order to be considered complete.
 * Beds and baths - If the lot is a residential lot, two drop-down menus&mdash;bed and bath&mdash;are available. These menus indicate the number of bedrooms and bathrooms, respectively, on the lot.
 * Lot value - This gives the current value, in simoleons, of all objects and architectural features on the lot.
 * Bulldoze Lot - This tool allows the player to delete all objects and features from the active lot. Clicking the icon brings up a prompt to confirm the selection.
