摘　　要：通过对单元测试模式的AutoCAD三维图形自动判别技术研究,利用Visual Basic、Visu-allisp编程语言以及图形格式转换、图形数据信息遍历搜索方法,解决了三维DWG图形批量自动打开并完成DWG至SAT数据文件格式的自动转换,并对SAT数据文件进行遍历搜索提取三维实体图形数据信息自动存储到Access数据库中,结合特征数据比对法实现CAD三维图形的自动评判、结果显示、数据输出等功能,为三维CAD测试实现网络化、自动化、无纸化奠定重要的基础。Through studying the automatic discrimination technology of AutoCAD three-dimensional graphics based on the unit test mode,the problems of automatic batch opening of the DWG graphics are solved.A nd automatic conversion of data format from DWG to SAT is achieved by utilizing traversal searching the SAT files,extracting the data information of the three-dimensional solid and storing it in the conversion technology and the traversal search method with graphic data information.Thus the automatic evaluation,result display and data output on three-dimensional CAD graphics is realized combining with the comparison method of the feature data which lay an important foundation for the three-dimensional CAD test to achieve networked, automation and paperless.
