Modeling is important because designers can use various modeling programs to create 3D representations of their proposed designs. These renderings are based on measurements taken by hand or with a CNC router. By using these models, designers can view their designs from different perspectives. They are also an attractive way to introduce the space to the structures. Modeling is extremely useful for placing furniture and appliances.A designer needs at least a superficial understanding of the mathematics behind their designs in order to create a convincing model. Mathematics is used to calculate dimensions and areas. While modeling requires less math than something like architecture, a good understanding of geometry can be helpful at this stage of the design process.3
