With the use of architectural modelling software, one can articulate and communicate ideas in ways not possible with other communication media. Architectural modelling gives you a much deeper understanding of how a project appears and functions as a whole. Today's architects/interior designers can design and stage a building or cityscape by animating light and colour, introduce structural detail, and show construction processes over time. At its best, a 3D model can do more than merely sell a design idea. It recreates the processes of construction and engineering before the clients' eyes, present shadow analyses, previews a landscape, shows architects where their designs fail, and provides a new way of integrating ideas between clients and designers, in real time. These interactive designs can ultimately shave weeks, even months from the traditional design, documentation, and approval cycle.
