Three dimension computer model full size grading system for processing a shoe model by a triangular geometry mode

A three dimension computer model full size grading system for processing a shoe model by a triangular geometry mode, said three dimension computer model full size grading system comprising the following steps:

• (a) a leading processing work:
• receiving triangular data,
• performing division of a common member,
• selecting characteristic lines,
• filling a grading table and a geometric relation table by a user, and
• inputting and storing said grading table and said geometric relation table in a data base;
• (b) a main processing work:
• inputting gauges of each engineering diagram,
• selecting each grading item,
• inputting parameters,
• automatically reading numbers and dimensions of each size stored in said grading table,
• reading data of each file and data of stick points of said common member stored in said geometric relation table,
• serially performing a grading operation processing on each geometric file of each size,
• building constraints in the whole group of triangular geometry to satisfy each grading specification in a local variation manner,
• finding geometric discontinuous positions which are caused by said common member for performing a repair work, and
• storing results of operation in said data base to respectively mate with positions of respective sizes;
• (c) a trailing processing work:
• setting C.A.M. parameters of base sizes,
• storing said C.A.M. parameters of said base sizes,
• analyzing geometric members being used by an inner program,
• deriving geometric members of new sizes from said data base for updating said geometric members of said new sizes,
• automatically calculating data of dimensions of all sizes for manufacturing a shoe model.
