文档介绍：摘要
在国民经济各个部门的建设和检修中,都少不了用金属制作各种构件,正确的展开放样是制作这些构件的第一道工序,它的正确与否对构件的质量和精确程度起着重要的作用。
有的钣金展开计算次数多,计算也麻烦,精度较低,错误率也很高,针对钣金展开的效率及精度,结合计算机绘图和AutoCAD二次开发,使用Lisp语言编写钣金展开图的程序,可以有效的解决上述的问题。
关键词:AutoCAD二次开发钣金展开
ABSTRACT
In the national economy each department's construction and the overhaul, could not all be few manufactures each kind ponent with the metal, correct unfolded the opening The type is manufactures ponents the first working procedure, it is correct or not is playing the vital role to ponent quality and the precise degree.
Some plate works launch putation number of times much, putation also troubles, the precision lower, wrong rate very isalso high, launches the efficiency and the precision in view of the plate work, unifies puter cartography and the AutoCAD Re-development, uses the Lisp language pile the plate work developed view the procedure. May solution above question effectively.
KEY WORDS : The AutoCAD Re-development plate works launch
