Input data (ID) representative of a model are stored in a computer installation (ST) in memory cells (DF1). The data-processing equipment operates with a program which is directed, by means of first signals (i1) generated by one or more first activations of terminal members (TER'), to generate, with the aid of the said input data, representations of the surface of the body in the form of contours of a number of vertical sections extending through the centre axis of the body. The contours are presented one at a time on the screen of the computer installation. By means of second signals (i2), the said program is directed to simulate on the crosssections/contours concerned an alteration or extension attributable to a variant of the model. With third signals (i3), the program is directed to store in memory cells (DF2) data attributable to the variant simulated by means of the altered or extended vertical sections. The latter data form or are utilized to generate output data (UD) from the installation (ST). |
