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]
Composition (visual arts) In the visual arts, composition is the placement or arrangement of visual elements or 'ingredients' in a work of art, as distinct from the subject. It can also be thought of as the organization of the elements of art according to the principles of art.
