Application Of Genetic Algorithm In Computer Aided Design

Design is a kind of creative activity that people take to realize certain special purpose. Itis also the most fundamental activity that people take to live and develop. All the procedureof man-made material requires design. The original purpose of design is to meet the demandof human beings so that design takes simplicity and utility as the main aim. With thedevelopment of society, people are no longer satisfied with the fundamental demand; theirdemand for design takes on the trend of personality and diversity so that the pursuit of beautybecomes the main aim of design.Reaserchers have pointed out many methods about design.The paper advance a newmethod of design that based on law and character. The design based on law combines geneticarithmetic (GA) with concrete CAD modeling technology. It takes the basic elements of thesweeping constructive entity technology as the chromosome of GA coding and then producecreative product after the operation of evolution.Creative design based on characters is an abstract method of design which is mainly usedin the phase of the combining of GA and product conception design. It converts the productdesign into the definition of the characters of the product and make use of GA to advancethese chanacters. For the same designing aim, It also show the differences between productsbecause the different choice of the characters.The paper's first three chapters analise the development of design, the statement of theresearch in the creative technology and the theory related to GA. This part is imperitive in thestructure of the whole thoery. The research for the development of creative technology showsthat the demand of the design technology is an ever-increasing procedure. The research intothe statement of design technology ensures the paper not to be done mechanically accordingto the precedent but an advance base on them. The basic thoery of GA is the basis of thepaper. In the paper we woundn't do further research into the theory but apply the ever maturetheory to the new research field and we also make use of it to find and settle the imergingproblem during the application.Of course, the successful compleion of experiment in the paper is greatly benefited fromthe ACIS mounding tool. No matter how mature the thought is, it must be testified in thepractice. The ACIS mounding tool provided by Spatial Company just offers the powerfulenvironment to support the completion.The fourth chapter of the paper discusses the creative design based on law.Body uint andface sweeping can be used in the method of entity generation. In ACIS, function can be usedto form law, then the law would be used to produce curve. Using the curve in different waydiffierent faces can be produced. Entities wound be generated if the face be sweeped incertain way. The chapter discusses the curve's function, starts encoding and evolution usingrelating theory of algorithm, form diverse filial generation entity according to consumer'svaluation.The fourth chapter combines GA with concrete moulding methods and form all kinds ofentities. During the reseach, we found that the combination of GA with CAD is just the...
