What are the advantages of cad package and compared to other methods model making?

CAD (Computer-Aided Design) packages offer several advantages over traditional model-making methods. Firstly, they provide precision and accuracy in design, allowing for easy adjustments and iterations without the need for physical materials. Additionally, CAD software enables 3D visualization, facilitating better communication of ideas and concepts. Furthermore, it streamlines the design process through automation and integration with manufacturing tools, ultimately saving time and reducing costs.
