Dynamic holographic model based on zero D

To meet the requirements of product variant design and rapid design,the method of building dynamic holographic model based on Zero D was proposed by analyzing the product model.In product conceptual design stage,the product design model was abstracted into the assembly sketch model,and various relations were added on it to integrate all kinds of information into product model.Thus the model could change and update based on design requirement.The effectiveness of proposed method was testified in crane design.
