The invention concerns a flat instrument (10) for drawing or cutting out geometrical shapes consisting of a thin transparent plate provided with markings and comprising at least first and second adjacent edges (11, 12) mutually perpendicular. The invention is characterised in that said instrument comprises, on its inner face, markings consisting of: first fine lines (L1x) parallel to said first edge (11), regularly spaced from one another with a pitch equal to a length measurement unit fraction and approximately ranging between 0.5 and 2.5 mm, the line adjacent to the first edge being spaced therefrom by the same pitch; and second fine lines (L2x) parallel to said second edge (12), regularly spaced from one another with the same pitch, the line adjacent to said second edge being spaced therefrom by the same pitch. The first and second lines extend in a substantially continuous way between the second or first edge of the instrument and an opposite edge (13).
Un instrument plat (10) pour le dessin ou le découpage de formes géométriques est constitué par une plaque mince transparente pourvue d'un marquage et comportant au moins un premier et un second bords adjacents (11, 12) perpendiculaires l'un à l'autre. Selon l'invention, cet instrument comporte, sur sa face inférieure, un marquage composé: de premières lignes fines (L1x) parallèles audit premier bord (11), régulièrement espacées entre elles d'un pas égal à une fraction d'unité de mesure de longueur et compris entre environ 0,5 et 2,5 mm, la ligne adjacente au premier bord étant espacée de ce dernier de ce même pas, et de secondes lignes fines L2x) parallèles audit second bord (12), régulièrement espacées entre elles du même pas, la ligne adjacente au second bord étant espacée de ce dernier de ce même pas. Les premières et secondes lignes s'étendent de façon essentiellement continue entre le second ou le premier bord de l'instrument et un bord opposé (13).
