这一辑做个程序绘制图框和标题栏，看了之后能充分体会到AutoLISP的工作原理

读完代码你会惊奇的发现，这不就是画图过程嘛：调用的command命令，一句一句的执行，一点难度都没有。lisp就是这样，很容易理解。(只要记住了第一辑讲的，呵呵!)- Y% W. Y* ]3 z8 c
看懂程序后对它稍微一改，就能做出符合自己要求的图框和标题栏，一劳永逸，岂不快哉。(注意：由于版本的变化，可能需要对程序稍作修改才能适应)1 R6 r; H& L& o- M' B+ h( I

楼主
ACAD帮助文件里就有开发人员帮助文档，也不错。还是那句话：遇到问题上论坛问，不就OK了。. i5 j s' j! Z1 H' P# K
