lisp will do it.

you want something like....

(setq thefile (file open "c:\whereitsat\thusnsuch.txt"))
and something like
(readline thefile)
in a (while thefile ......
(setq point
(cons.....
[dxf list]
)
(entmake point)

)

LOOP.

check out the help files in vlisp.

I did it once for a fella at Burns & Mac, he wanted ascii data into
autocad
it looked like this that time:

(defun c:andy (/)
(setq file (open "c:/file.txt" "r")
from (read-line file)
to (read-line file)
)
(setq pt1 (cons (atof (substr from 1 6)) (atof (substr from 8 6)))
pt2 (cons (atof (substr to 1 6)) (atof (substr to 8 6)))
)
(setq ent (list (cons 0 "line")
(cons 100 "AcDbEntity")
(cons 8 "0")
(cons 100 "AcDbLine")
(list 10 (car pt1) (cdr pt1))
(list 11 (car pt2) (cdr pt2))
)
)
(entmake ent)
(repeat 1000
(setq from to
to (read-line file)
pt1 (cons (atof (substr from 1 6)) (atof (substr from 8 6)))
pt2 (cons (atof (substr to 1 6)) (atof (substr to 8 6)))
ent (list (cons 0 "line")
(cons 100 "AcDbEntity")
(cons 8 "0")
(cons 100 "AcDbLine")
(list 10 (car pt1) (cdr pt1))
(list 11 (car pt2) (cdr pt2))
)
)
(entmake ent)
)
(close file)
)

ugly code, that, but it worked with the way his data was formatted, and
we only needed it once.

cheers.
