​In the last decade, a new type of design software has emerged that has fundamentally changed the way that architects use computers and develop their designs. These tools, known as parametric design software, allow architects not only to model the final design solution but also to describe the entire design process itself. During this process then architects define specific values called parameters, that can be used in this process to control the whole design. Although such a model requires more work at the beginning, it offers to architect many advantages and in the end, it helps to find the most suitable solution within a very effective time frame.
     n architect can quickly generate different design variants by changing input values, avoiding the manual and tedious creation of individual option that often fail to meet their best solutions. The parametric model is absolutely adaptable to changes in the future. Because the model is defined by a series of operations,  it is possible to adapt the design to changing conditions very easily instead of always building the model from zero. Most importantly,  the parametric approach allows an architect to think through all the design solutions deeper and more dynamic than it is possible with traditional 3D or 2D methods.       
   With parametric principles, besides the classic design process, where an architect studies a problem, internalizes all his constraints and goals, and uses his ability and experience to find the solution, all the constraints and goals can be used as part of a single parametric model that generates possible solutions.
