Abstract: In current three-dimensional model parametric variations, there exist the problems
of unreasonable view layout ,imbalance, and marked confusion after drawings change, and also
the technical limitations of adjustment. In this paper, the immune genetic algorithm is used in
drawings optimization and adjustment. Based on the template parameter driven, it realizes
drawings automatic generation and optimization in view of layout and proportion, and its various
label location. It has been proved that the method can realize intelligent rapid drawing, ensure the
accuracy of the design, and improve design efficiency and quality.

Key words: parametric variant design, immune genetic algorithm, drawing automatic
generation and optimizing, intelligent rapid drawing
