Hi everyone 🙂

I want to know can i make lisp save some data i have calculated inside from a drawing to a text file.

I know one command in AutoCAD can make this (MassProperties)

Can this be achieved by LISP code .

Thanks for all

Once you have a file open for writing, you can write to that file. Or if you are just trying to write out the massprop output

(command "._massprop" ss1 "" "_y" ""); ss1 is a selectionset of objects

Of course it can.

What values are you looking to export?

A sample DWG file would be good for us to look at; sample output too.

You will probably have to specify a precision for real numbers.

I have searches and find something that worked correctly with me

(setq F_P (getfiled "OPERA_Stair" "" "txt" 1))
  (setq F_P (open F_P "W"))
  (write-Line (strcat 000A) F_P)
  (close F_P)

It appears that the strcat wasn't necessary, but YOU GOT IT!

And you can write as many lines as you want before closing the file.

I do presume that 000A was actually a string variable. You can write-line only strings to a file.

I know @john.uhden

it's just a quick thing i have written here. In my full code i use Strcat to write many strings.

and yup 000A is a predefined variable i used in mu code.
