The image of three-dimensional bodies on a plane is associated with the obligatory observance of certain conventions. Drafting conventions are different from other image methods, and knowledge of them is mandatory for everyone working with drawings. The pamphlet, in popular form, outlines planar imaging techniques. The focus is on orthographic design conventions. The author's illustrations complement the main text. Designed for a wide range of readers, the brochure can serve as a guide when studying a drawing course in schools, colleges and technical schools.
