The CTRL Key: When painting/covering walls, holding CTRL will un-paint a single section of wall, returning it to its initial, bare appearance. Many objects will automatically duplicate, like trees and windows. When placing some objects, holding SHIFT will duplicate the object.
In The Sims 2 or later, there is a tool specifically for creating rectangular rooms. This can be done with half walls and fences as well. When placing walls, holding SHIFT will create square or rectangular rooms. When placing flooring, holding SHIFT will place flooring in the selected area. If the wall creates a complete room, holding SHIFT will paint the whole room at once.
The Shift Key: When painting/covering walls, holding SHIFT will paint the whole wall section at once. For example, all Build Modes make use of the same keys for performing actions.
If one is already adept at using one version of the Build Mode, other versions can be mastered with very little effort.
In The Sims, The Sims 2, The Sims 3, and The Sims 4, build modes are all relatively similar. Regardless of the version of the game being played, building using the game's Build mode can be made simpler with some basic knowledge, use of the correct key combinations and use of suitable Build Mode Tools.
