The sketching machine has a casing (3) of parallelepipedal form with, on its front face (9) an optic (13) with its axis (xx) perpendicular to the face. A transparent or translucent plate (27) is integrated with an upper face (25) orthogonal top the front face. A mirror (29) is situated inside the casing angled around an axis (yy) parallel to the axis of intersection (zz) of the planes containing the front face and the upper face (25). The machine has an adjuster (11) for the focal length of the optic to allow the reflected image point by the mirror onto the transparent plate.
