基于ObjectARX三维模型切片软件的开发

Development of direct slice software on three-dimensional models using ObjectARX

提出一种新颖的直接切片方法 ,用于快速原型制造领域。即利用AutoCAD的二次开发工具ObjectARX开发一个动态链接库 ,运用于AutoCAD的集成开发环境中 ,实现三维模型的直接切片。同时自行开发一开放接口 ,用多层表数据结构存储每一层切片轮廓数据 。

A novel direct slice method is proposed in the application of Rapid Prototyping Manufacturing field. A dynamic linked library is developed using ObjectARX in order to realize direct slice on three-dimensional models in the integration development environment of AutoCAD. Moreover, an open interface is specially developed as well as slices data can be independent of AutoCAD, accordingly, a multi-layer table data structure is devised to store details of the slices contours.
