在实际实践中，许多新的机械零件都是通过修改现有零件来设计的。通过这种方式，可以节省时间和精力，而不必从头开始设计零件。如果有一种有效的方法来搜索现有的类似设计，设计时间将进一步减少。此外，一个新的零件设计可以非常有效地通过修改现有零件的特征上的尺寸，如果一个零件具有相似的特征集和相应的建模history.In的部分可以很容易地从现有的零件库中搜索。首先比较整体外观，然后比较详细特征。通过这种方式，可以从零件库中识别除了具有相似的总体形状之外还具有相似特征集的现有零件。一旦识别出相似零件，如果现有零件是由基于特征的建模者设计的，则其建模历史也可以用于参数化建模。(C)2006爱思唯尔有限公司保留所有权利。
In actual practice, many new mechanical parts are designed by modifying existing ones. In this way, time and effort can be saved by not having to design parts from scratch. Design time would be further reduced if there were an efficient way to search for existing similar designs. Furthermore, a new part design can be very efficiently generated by modifying the dimensions on the features of the existing part if a part with a similar feature set and the corresponding modeling history can be easily searched from the existing part library.In this paper, a two-step similarity comparison method for B-rep files is proposed. Overall appearances are compared first, and then detailed features are compared. In this way, existing parts with similar feature set in addition to similar overall shape can be identified from the part library. Once the similar part is identified, its modeling history can also be used for parametric modeling if the existing part was designed by a feature-based modeler. (C) 2006 Elsevier Ltd.
