3D floor plan can be defined as a virtual model of a building floor plan. It's often used to better convey architectural plans to individuals not familiar with floor plans. Despite the purpose of floor plans originally being to depict 3D layouts in a 2D manner, technological expansion has made rendering 3D models much more cost effective. 3D plans show a better depth of image and are often complimented by 3D furniture in the room. This allows a greater appreciation of scale than with traditional 2D floor plans
