Please help me modify the lisp program for importing the data from .txt
This is how data looks like:

the first number is object code, second is X coordinate and third is Y coordinate I need program to draw SEPERATE objects with data like that.

Firstly the data has an error in the first line 2.117.428999999954 should read 2117.428999999954 The first decimal is incorrect. Next consider the attached lisp routine:
(defun initiate () (setq filename "data.txt" fileopen (open (findfile filename) "r") ) ) (defun c:separate () (setq line (read-line fileopen) delimiter1 (vl-string-search "," line) delimiter2 (vl-string-search "," line (1+ delimiter1)) dat1 (substr line 1 delimiter1) dat2 (substr line (+ 2 delimiter1) (1- (- delimiter2 delimiter1))) dat3 (substr line (+ 2 delimiter2)) codeno dat1 coord (list (distof dat2) (distof dat3)) ) )
This routine assumes your data file is named data.txt . You can change this by changing the filename variable. Assuming the data file is in your AutoCAD search path, to run this load it and then enter "separate" without the quotation marks. The first line of the data file will be broken up into 5 entities dat1, dat2, dat3, codeno & coord. dat1=codenoÚt1. dat2=xcoordinate as a string. dat3=ycoordinate as a string & finally coord is the list of your x and y coordinates which can be used by AutoCAD. for example if you wish to draw a line from the first coordinate point type in "l" to start the line command and then !coord to use the coordinate as the first point. To retrieve subsequent data lines just run "separate" again. When you are done enter (close fileopen) at the command line. To start over enter (close fileopen) then (initiate) then "separate".

Jeff, there are two problems with your program; it doesnt work if the start object code is NOT = 1 and if any object is skipped. Could you please modify it so it would work with this data file:

Hi, I thought you'd forgotten about this since there was no response for 11 days. I'll take a look at it in the next day or two.
Would you be willing to send me a complete point file? If so, send to: jmishlerATsbcglobalDOTnet adjust the AT & DOT accordingly

Hi orangeKDS, I just looked and realized it wasn't too hard of a fix. Here's a new lisp that works with any leading number, in any sequence (providing the same number sequence is not repeated, otherwise they will be all created as 1 pline).
This one also should be much quicker.

Hi, could you do one more modification, hope its not too hard:
the new data would look like this:
LineCode, Xcoordinate_of_first_dot, Ycoordinate_of_first_dot, ASCIItext, line density LineCode, Xcoordinate_of_next_dot, Ycoordinate_of_next_dot,, line density
this time Line must NOT be closed, I have tried modifying your program like this: (vla-put-closed pline :vlax-true) to (vla-put-closed pline :vlax-false)
and it works, but how can I add ASCII text next to line and change its density?

If you take your *.txt file and rename it to *.csv it will open in Excel. If you add two columns in Excel, Z coordinate and Description could make use of our survey program: http://www.caddproductivity.com/survey.htm
It's an add-on VB program which imports and exports survey data to & from AutoCAD. The download is fully functional and free to use for 30 days.
From the website:      Survey Import and Export
The Survey program works to Import and Export your survey data to and from AutoCAD®. The configurable interface makes matching survey data descriptions (as assigned in the field) to text, blocks or points, straightforward.
Import Survey Data: Survey data is read from *.txt or *.csv file(s) so the user may match the data to blocks, text or points per unique description. The selected descriptions are inserted in to the drawing per the symbols specified (with the option of coordinate marker blocks, which display coordinate & other data). Import Survey Data works with the supplied database (CADD.mdb included with the program's installation file) to support multiple (saved) import configurations.
Interactive Image: www.caddproductivity.com/surveyimage.htm
Export Survey Data: Blocks and text are exported from the drawing to a text file (containing X, Y, Z, Index and Description) via a configurable interface.
