what is used by architects and engineers to create diagrams and graphical drawings
Architectural drawing The development of the computer had a major impact on the methods used to design and create technical drawings,[1] making manual drawing almost obsolete, and opening up new possibilities of form using organic shapes and complex geometry. Today the vast majority of drawings are created using CAD software.[2]
Mathematician To develop accurate models for describing the real world, many applied mathematicians draw on tools and techniques that are often considered to be "pure" mathematics. On the other hand, many pure mathematicians draw on natural and social phenomena as inspiration for their abstract research.
