The general architecture of the integrated environment is divided into five tiers and employs the transparently integrated mode, with the mode, function calling and information exchanging among independent PDM and CAD processes are carried out via message translation /parse approach. Product layout feature（PLF ） model definition is presented, PLF model is used to represent design intention at the preliminary design phase. The collaborative design methodology employing the PLF model in PDM/3D CAD integrated environment is analyzed. The design methodology can speed up the design process, reduce the investment and improve the product quality.展开更多

Inspired by an Exquisite Corpse gameplay, our tool allocates distinct parts of a shape to multiple players who model the assigned parts in a sequence. Our approach is motivated by the understanding that effective surprise leads to creative outcomes. Hence, to maintain the surprise factor of the output, we conceal the previously modeled parts from the most recent player. Part designs from individual players are fused together to produce an often unexpected and novel end result. We investigate the effectiveness of collaboration on the output designs by conducting a sequence of user studies to validate the hypotheses formed based on our research questions. Results of the user studies are supportive of our hypotheses that multi-user collaborative 3D modeling via ExquiMo tends to lead to more creative novice designs according to the commonly used criteria for creativity： novelty and surprise.展开更多
