为了更高效地提取MBD模型工艺信息,提出基于改进递归深度优先遍历算法的MBD模型工艺信息的提取方法,详细介绍了此方法的应用过程.该方法以Visual Studio2012为平台,将模型的组成信息和工艺信息存入多叉树中,通过构建和遍历多叉树,运用层级控制,可以只遍历任意一段子树并输出其信息,避免了遍历全部信息的情况.借此不同职位工作者根据自身需求,可只遍历和输出所需内容.最后辅以实例验证了该方法的可行性,并且越是复杂的模型,其优越性越明显.%To extract the technology information of MBD model, this paper proposes a method based on improved recursive depth-first search algorithm.It introduces the process of the method concretely.The method took the Visual Studio2012 as platform, and achieved the goal of traversing and output the information of arbitrary subtree through saving the composition and technology of the model into multi-tree, building and traversing multi-way tree, using the hierarchical control, which avoided the situation of traversing all information.In this way, different workers in diverse positions just traverse and output the content they need according to individual requirement.Eventually, an example was quoted to demonstrate the feasibility of the algorithm.More complicated the model is, more excellent it is.
