The development of AutoCAD optimal cutting program based on ObjectARX and genetic algorithm

Sheet metal cutting is a necessary activity for effective production,AutoCAD is a general computer design and drawing software for placement,and AutoCAD is also easy to be carried out secondary development.in this paper,the research and discussion on ObjectARX which is a tool for developing AutoCAD 2007 have been developed,analysis the process of secondary development based on ObjectARX,describe the key technology for procedure of optimal layout in detail and the methods of custom orders for the secondary development,then the exploitation of cutting program which is taking ObjectARX as foundation,taking Visual Studio 2005 as developing environment,taking genetic algorithm as optimal algorithm has been implemented,and after all the optimal cutting program used for automatic layout has been carried out in AutoCAD.The method has been proved to be be useful through layout example finally.
