高手帮忙看一下添加文件搜索路径的lsp

shep2008

在网上找到一个添加路径到CAD文件搜索路径的lsp如图所示位置，不知道要添加到哪里，请高手指点一下，例如我要添加D:\AutoCAD1和D:\autocad2两个路径，要怎么改下面的代码：

代码我话到二楼去了，放这里不会自动换行

(defun Example_SupportPath ()

;;;这个范例返回

;;;SupportPath的当前设定值，接着改变它的值，最后恢复初始值

(setq AcadObject (vlax-get-acad-object)

mSpace (vla-get-ModelSpace AcadDocument)

(setq preferenceSel (vla-get-Preferences AcadObject))

昨天的有误，今天更新如下：

代码很好用，谢谢分享。我修改了一下，这样就可以放在最前面或最后面：

(setq sp (getenv "ACAD"))
(setq path '("D:\\autocad1" "D:\\autocad2" "D:\\autocad3"))
;(foreach x path (setq sp (strcat sp ";" x))) ;文件搜索路径放在最后
(foreach x path (setq sp (strcat x ";" sp))) ;文件搜索路径放在最前
(setenv "ACAD" sp)

学习了~

2. (setq sp (getenv "ACAD"))
   
3. (setq path '("D:\\autocad1" "D:\\autocad2" "D:\\autocad3"))
   
4. 
   
5. (foreach x path (setq sp (strcat sp ";" x))) ;文件搜索路径放在最后
   
6. ;(foreach x path (setq sp (strcat x ";" sp))) ;文件搜索路径放在最前
   
7. 
   
8. (setenv "ACAD" sp)
   
9. 
   
10. (princ)

(setq sp (getenv "ACAD"))<br /> (setq path '("D:\\autocad1" "D:\\autocad2" "D:\\autocad3"))<br /> <br /> (foreach x path (setq sp (strcat sp ";" x))) ;文件搜索路径放在最后<br /> ;(foreach x path (setq sp (strcat x ";" sp))) ;文件搜索路径放在最前<br /> <br /> (setenv "ACAD" sp)<br /> <br /> (princ)

        (setq supportlist (append supportlist (list PathToAdd)))
      )
      (setenv "ACAD" (strUnParse supportlist ";"))
    )
  )
)
(AddSupportPath "D:\\autocad1" nil)
(AddSupportPath "D:\\autocad2" nil)

说明：当isFirst参数为“nil ”，添加路径到末尾，否则为开头。

先去试一下，谢谢！！

好像不行啊。只能添加一个。。
还有我记得好像可以添加到第几列的？可以设置吗？

是可以添加多个目录的，前提是这些目录是真实有效的。
如：我的c盘局部截图：
我原来的文件搜索列表：
添加后：

另外关于添加位置的问题，其实在什么位置是无关紧要的，只是有搜索的先后而已，如果有目录需要先搜索，可以加载其到开头。如上例的test1

多谢zhynt热心指导
会那么多,真佩服您.您做什么工作啊?
我做市政等设计,编autolisp程序纯粹是爱好,有时还挺上瘾,不过是挺费时间的.

您也是自学的吧,一边上班赶图,一边学编程---真的挺辛苦
您要是一线设计人,是不是也总加班啊.
我们基本就没歇过完整的假期.
