Abstract: The invention relates to a reusable device for creating a model or reproducing a subject manually from life (3D subject) or by means of scaled or non-scaled duplication (flat or cylindrical subject). The inventive device comprises an overhead transparency (1) which has been pre-perforated to form a regular distribution of holes (1.a) over the entire surface thereof and a not-perforated overhead transparency (2). Said two overhead transparencies are stacked on top of one another such as to enable a subject (3) to be aimed and reproduced. A first drawing is divided into two complementary layouts (6/1) and (6/2). Depending on the case, the layout (6/1) can be used as it is (without being transferred) or it can be transferred to a support (7). The result (8/7) is obtained through the overhead transparency (1) which is put alone on the support (7), by drawing again over the layout (6/1). The device also comprises other components.
