Extracting X,Y, coordinates with Handle

[Drafty]

Either an Excel file or .CSV file would be fine.

 

Pline1 xy xy xy xy

ITRP;

33624;

52;

 

Ideally one column per line of text.

[BIGAL]

This code works but found out a few things like if text is contained within 2 polygons it will find it twice. If I run it on your dwg it does not work, if I copy bits of your dwg then it works I am not sure what is causing error maybe something about blank polygons with no objects. Will try to find

(defun getcoords (ent)
 (vlax-safearray->list
   (vlax-variant-value
     (vlax-get-property
   (vlax-ename->vla-object ent)
   "Coordinates"
     )
   )
 )
)

(defun co-ords2xy ()
; convert now to a list of xy as co-ords are x y x y x y if 3d x y z x y z
(setq numb (/ (length co-ords) 2))
(setq I 0)
(repeat numb
(setq xy (list (nth I co-ords)(nth (+ I 1) co-ords) ))
(setq coordsxy (cons xy coordsxy))

Good work BigAl, Cheers.

What is the command line text i should type in to run the programme?

[BIGAL]

I have been trying to get it to work and found a few problems your polygons are doubled up and possibly overlapping line work and so does not work, if you just draw a closed pline put some text in will work. I have not finished it because it will not work properly with your drawing but any I make works perfect.

 

Just save the code via Notepad call it say text in poly.lsp then appload "text in poly" it will ask for selection pick all on screen.

 

Somebody out there ? any suggestion re his drawing ?

[Drafty]

i keep getting this error when trying to load it:

 

Getpoly.lsp successfully loaded.

Command: ; error: syntax error

Command:

[BIGAL]

When you copied it into notepad did you copy all of it you must scroll down, I copied it from here and ran it works ok.

[Drafty]

ahh yes, that now works in as much as i can select multiple polylines. i recive this error instead whether i select items from the existing drawing or from a new drawing:

 

Select objects:

; error: no function definition: VLAX-ENAME->VLA-OBJECT

Command:

 

Did you manage to successfully output the information into an excel spreadsheet?

[BIGAL]

Hi Drafty

 

First add (VL-load-com) as first line of code, second I stopped because I could not get it to work with your drawing, I need help anyone out there ? something about your drawing.

 

As a test just draw a few closed plines add some text and mtext you should see result on screen press F2. this is what would be output plus co ordinates.

[Drafty]

It appears not to work in my drawing as you have confirmed. I then created a new drawing with some MTEXT and got this result in the command line:

 

Select objects:

test\P123\P56\Pgreen

 

Where are the coordinates though?

 

I will have a play round with my drawing some more to see if i can ascertain the issue.

 

Thanks for your persistance with this :-)

[BIGAL]

As I implied I didn't finish it the x y variables are in 2 places co-ords & co-ordsxy just two different ways of making a list of the co-ords. I was just going to write out co-ords as excel will read it as space delimited.

 

old (setq co-ords (getcoords obj))

new (setq co-ords (getcoords obj))
(princ co-ords)

[Drafty]

I have copied the entire contents of the drawing and pasted it into a new file. When i run the lisp routine it now picks up the polygons and text. Maybe the file has corrupted or something?!

[BIGAL]

Will try to find time I dont have much spare time at moment to finish

[BIGAL]

Have a look at this needs some refining not much time at moment use space delimeted into excel

Enter file name test

Select objects: 1 found

Select objects:

[fixo]

my guess

(vl-load-com)

is missed, put this one at the start of lisp

[Drafty]

Thanks for the reply fixo. I have now got this error message!

 

Select objects:

Thanks fixo

 

Drafty please post dwg

[Drafty]

BigAl,

I have attached the drawing that you are familiar with along with a new one which contains two polygons and text inside each of them.

 

The error message comes up on both drawings so i imagine its not drawing related?

 

Thanks

Existing Basket.dwg

New Basket.dwg

[pBe]

as Bigal already noted on the lisp

; choose output file change acdatemp to what you want

 

make sure this folder exists "c:/acadtemp/" otherwise change it to whatever folder you want. [existing that is]

[Drafty]

pBe,

Thanks but i still get the same error message
