[1123]请教如何撷取图层资料输出到TXT档案中呢?
请问各位高手们
如何才能够将图层中的,图层名称.图层颜色.图层笔号.这些资料
输出到TXT档案,且也可以透过这方式,
在回传输入到CAD档案中的图层.

小弟查到应该是要运用以下这些命令
但不是全部
(setq dat_file (getfiled "输出资料档案" "c:\\test" "txt" 1))
(setq ff (open dat_file "w"))
(write-line "图层名称线型名称颜色编号" ff)
(write-line (strcat "\n<" (layna) (comm) (colornu) ) ff)
(close ff)
)

(tblnext "layer")
;配合符号表的群码2 图层名称62 颜色编号6 线型名称

目前遇到问题是,如何才能够执行重复的图层名称判断
及输出栏位资料的位置该怎样控制

如果论坛有相似的文章,或是范例
请各位告知,就可以去参考一下了
希望各位帮忙解答一下
谢谢

最简单的方法是ASCII的DXF文件，只是你必须了解DXF文件结构和DXF组码！

那想请问这程式的开头要怎么写呢
因为dxf的资料有提供不选取就读取整张图面资料的代码吗

以下是找到的一个程式,应该可以完成输入的程序
程序中使用entmake产生layer会有茫点
就是如果layer已存在它是不会改变的
线型颜色等设定不会依你的设定,这问题有办法解决吗?

程序内容如下:
(defun c:tslisp01 ( / data ff)
  (setvar "cmdecho" 0)
  (setq FF (open "c:\\LayerData.txt" "r"))
  (setq DATA (read-line FF))
  (while (/= DATA nil)
(setq DATA (read DATA))
(if (= (type DATA) 'LIST)
   (progn
(entmake (list '(0 . "layer")
                     '(100 . "AcDbSymbolTableRecord")
                     '(100 . "AcDbLayerTableRecord")
                     (cons 2 (nth 0 DATA))
                     '(70 . 0)
                     (cons 62 (nth 2 DATA))
                     (cons 6 (nth 1 DATA))
               )
      )
   )
)
(setq DATA (read-line FF))
  )
  (close FF)
(prin1)
)

;LayerData.txt档内容如下
图层名称  线型       颜色
("0"    "CONTINUOUS" 7)
("1"    "CONTINUOUS" 1)
("2"    "CONTINUOUS" 2)
("3"    "CONTINUOUS" 3)
end

网上找的，试过一次，只能导出，不能导入，就没再用！
