Application Study of the Virtual Freeform in Product Development Design

In order to make the design of modern complex software support the multi-disciplinary optimization,realize its solving function,and confirm its comprehensive optimum scheme,We put forward a modeling method,which is combining the Freeform with surface design. Considered the characteristics of modern software design,we analyzed the important role that modern software played in the modeling process,studied the application process of modeling that combining freeform with the surface design.,and did the application of virtual design,for example,combined the technology of virtual claywith force feedback into the virtual design. Put the above method into the product design,and we confirmed that this technology can add or reduce the soil in accordance with the different demands, and is an effective method to solve the complex problems in the modeling process.
