ABSTRACT:
A method for constructing a three-dimensional laminar body of large dimensions is provided. Starting from a true-to-scale model of the three-dimensional laminar body to be obtained, which comprises the entirety of said body or parts thereof, one or several negative molds which unitarily or together comprise the entire working surface of the three-dimensional laminar body are shaped on the model, and then used to mold, with a fine finish, the entire three-dimensional laminar body or the different constituent parts thereof.
