Design And Realization For CoLaborative Design System Based On B/S Style

With the development of the base theory and application of CAD technologies, designers' requirements to CAD system become higher and higher. Obviously, "throw away the drawing table" is not enough. Designers hope that burdensome and easy job is litter and litter, so they can concentrate on creatively thinking on a higher level. Because the Three-Dimension CAD system has the characters of visible ability, visualize ability, efficient ability and its ability of supplying designing information, manufacturing information and craftwork information for various application processes in the enterprise's digitalization, the Two-Dimension CAD system is historically replaced by Three-Dimension CAD system without fail.Based on the development of Computer science, Graphics technologies, Web technologies and Database technologies, this paper does a deeper research into Virtual Design technologies that is up to date in the development of 3D CAD technologies. Use Graphics technology as a base, Web technology as a style, Java3D technology as a manner, through the database and the arithmetic on 3D Parts Assemble invented by self, combined with the "Up-Down" and "Bottom-Up" design methods, this paper demonstrates the feasibility of building Virtual Design platform on the internet explore, and gives out all the details on how to building the Virtual Design platform.At the same time, combined with the author's understanding of CoLaborative designs which is one of the future develop direction of Virtual Designs, after studying how to build easy and operative CoLaborative design environment, the author brings forward the answer that is building the CoLaborative design platform on the Web. By ASP and Java technologies, the author turns the platform into reality.In the end, a mode of gear assembling process is given under the CoLaborative design platform the author designed. Aim at the possible problems that maybe appear in the designing process, the author gives his own opinions.The platform described in this paper can be turned into reality under the condition of which there is only Internet Explore and database can be used. At thesame time, because of the advance characters of computer software technologies used in designing the platform, the platform can be installed on various Computer Operative Systems through litter changes or no changes. So, at some aspect, the platform can be told that it is one of the most simple and convenient Colaborative design systems on the world now.
