HOw to extract data from read-line command

Hi,

I want to know how can I dequote so to say, a reading from a read-line command.

To be more specific, I have a TXT file with coordinates and heights, space delimited, and I would like to read the whole line (or parts of it) as not string.

expl:

...read-line -> "97451586.021 4869451.235 268.256"...

well I wan't to know how can I extract the data between the quotation marks

Thanks

What are you going to do with the data once it is read?

Well I was just thinking about that.

For now lets just say, I want them in the drawing as points.

How would I go about that?

You might use a custom lisp program like Lee Mac's Point Manager.

Thanks man!

You're welcome aleksa, glad it helps

For space-delimited data, you can also use the following 'shortcut' to interpret the data:

(read (strcat "(" <your data> ")"))

Even better.

I was actually looking for something like this!

Thanks to all!

Also...

(setq str "123.123 456.456 789.789")
(setq Xcoord (substr str 1 (vl-string-position (ascii " ") str)))
(setq Ycoord (substr str (+ (vl-string-position (ascii " ") str) 2) (- (vl-string-position (ascii " ") str nil T) (vl-string-position (ascii " ") str))))
(setq Zcoord (substr str (+ (vl-string-position (ascii " ") str nil T) 2) (- (strlen str) (vl-string-position (ascii " ") str nil T) 1)))
(setq point (list (read Xcoord) (read Ycoord) (read Zcoord)))

E Marko, hvala ti!

Bas sad gledam u Help-u taj SUBSTR. Još i ponajbolje rešenje.

Nema na cemu, Aleksa... Inace ako imas zareze u stringu, samo promeni (ascii " ") u (ascii ",")... Inace zarez je cest delimiter kod CSV fajla (C-Comma Delimited) koji je cesto u upotrebi pri koriscenju transfera podataka ACAD EXCEL...

Puno pozdrava i nema na cemu, M.R.

Hi

I dont know what the program does and whether I'm at work using PDMS

Thank you

Hi

The program is designed to run on AutoCAD and other software that enables AutoLISP & Visual LISP functionality (such as Civil3D / MEP etc.), to my knowledge, PDMS doesn't permit the use of AutoLISP or Visual LISP.

As for what the program does, please read the description on my site.
