The invention concerns a master model (1) defining a useful surface having a complex shape, comprising a set of juxtaposed frames (2a, 2b, 2c.), each frame comprising a panel having a useful edge (8), the frames being disposed parallel and held rigidly connected with predefined spacings such that the useful edges of same form the useful surface. The panel of each frame comprises a blind slot (10) forming an opening passing through the thickness, and the frames are rigidly connected by a spar (3, 3a, 3b, etc.) suitable for being inserted (6) in the lengthwise direction (L) of same into the slots and comprising transverse notches (11) for receiving and holding the frames, each notch being arranged to receive, by a relative transverse translational movement (7) of the spar relative to the frames, the part in question of the panel of each frame. |
