A dimension floor plan is a drawing to scale in architecture and building engineering, showing a view from above of the relationships between rooms, spaces, traffic patterns, and other physical features at one level of a structure. Since it is a dimension floor plan, every room, including the outdoor area and the plot dimension, should be ratioed. With the given dimensions, a floor plan will let the designer know the actual size plan of the floor. By creating a dimension floor plan, a designer can scale drawings that will provide a way to visualize how people will move through space. In a floor plan design, space planning is essential in new structures, but it’s also important in rethinking existing spaces to determine how to use them more efficiently.
