程序不全，例如ac_bonus.lsp

jack2913

请alin再说清楚一点做法好吗，我还是不太清楚，我是从r14里拿出来的，希望能在2004里用，谢谢你了

jack2913发表于2004-11-9 21:03:00请alin再说清楚一点做法好吗，我还是不太清楚，我是从r14里拿出来的，希望能在2004里用，谢谢你了

ALIN是叫你拿全面一点，不要拿一点不拿一点，少一点程序就断了。

meflying

不建议这样做,如果没猜错的话,这应该是R14中bonus工具中的内容,相当于2000及以后版本的EXPRESS TOOLS,这是一套工具,你仅拿出其中的一部分,要求修改,这是不可以的,而且这个需要修改的并不会是LISP程序,LISP程序基本上是通用的,不用修改,但其中如果有ARX或别的东西,就不能通用了,是无法修改的...


2004建议直接使用EXPRESS TOOLS工具,应该有类似功能的命令

jack2913

meflying太感谢你了，我试试看

jack2913

meflying:


                                                                                 在2004的EXPRESS TOOLS工具里没这功能，可以的话，帮我组织一下需要14里的那几个lisp,我再试试看，我敢决这lisp曼好用用的，谢谢你的协助！！！

meflying

我5楼说的那么多话都白说了?


前一个原因我说了那么大一段,可你为什么就只看到后面那一段中的可能性?如果EXPRESS TOOLS里没有就没办法了(原因就在前一段说明了)......


我看你上面引用的这个程序,应该是超级剪切吧,,,EXPRESS TOOLS里面怎么可能没有?你仔细看了吗?
