Patent ID: 8126682

Claim:
A design support system, comprising: a database which divides a history of design work for creating a shape model, comprising a first reference surface, for each part of the shape model and holds a plurality of design work histories as unit work history data, the database accumulating technical conditions, which are to be met by a part shape model to be created according to each unit work history data, in association with each unit work history data; and a control section configured to: fetch at least two unit work history data selected from the plurality of unit work history data held by the database; combine the at least two selected unit work history data and output design work data for creating a combined shape model, comprising a second reference surface, which is formed by sequentially reproducing the selected unit work history data one by one in accordance with an inputted user approval for each input work history datum and joining part shape models corresponding to the respective selected unit work history data; create a corresponding surface group in accordance with user input of a correspondence between the first reference surface and the second reference surface; determine, using the corresponding surface group, errors in the combined shape model arising from the second reference surface; compute at least one technical characteristic value of the combined shape model which is created from the output design work data; and compare the computed technical characteristic value with the technical conditions related to unit work history data which is the origin of the design work data; wherein the computation of the at least one technical characteristic value comprises analyzing the strength of the combined shape model, and wherein the errors determined using the corresponding surface group include at least one of a change of a number of configuring surfaces, a change in direction or quantity of border lines, reversal of a direction of a surface, and folding of a surface.
