title 
Drawing as Transformation: From Primary Geometry to Secondary Geometry 
source 
International Conference on Generative Art 
summary 
A distinction is made between primary geometry, the arrangement in space of lines of projection from a 3D object to a plane of projection, and secondary geometry, the relationships between the points, lines and shapes of the drawn projection on a 2D surface. Drawing projection systems, such as those classified under British Standard 1192, are illustrated, and are shown to be defined in terms of primary geometry. It is argued that a reclassification of projection systems in terms of secondary geometry enables firstyear students of drawing to relate more easily such systems of geometry to their observational experiences. Student drawings illustrate the argument.
