How to read polyline vert to file with name?

[iztok13]

Hello,

I have problem to make lsp file, that will read vertices of polilyine x,y,z coordinates to txt file with named polyline.
I have a bunch of polyline and i need to mark them with name and attach x,y,z coordinates of them.
So basicly i need to pick the polilyine, then must ask me the name of polilyine then record in to the txt file with the name and coordinates x,y,z. I have a lot of them so i need to be asked for another polyline and again and again and put to same txt file.

any suggestions?

[Lee Mac]

Perhaps this?



(defun c:plco (/ File oFile pLin pStr nlist pLen wLine)
(if (setq File (getfiled "Create a Text File" "C:\\" "txt" 9))
(progn
(setq oFile (open file "W"))
(while (setq pLin (ssget ":S"
(list (cons 0 "LWPOLYLINE,POLYLINE")
(cons 410 (getvar "CTAB"))
) ;_ end list
) ;_ end ssget
) ;_ end setq
(sssetfirst nil pLin)
(if (/= (setq pStr (getstring t "\nSpecify Name for Selected Polyline >> ")) "")
(progn (foreach x (entget (ssname pLin 0))
(if (eq 10 (car x))
(setq nlist (cons (cdr x) nlist))
) ;_ end if
) ;_ end foreach
(setq pLen (length nlist))
(while (not (minusp (setq pLen (1- pLen))))
(setq wLine (strcat (rtos (car (nth pLen nlist)) 2 2)
","
(rtos (cadr (nth pLen nlist)) 2 2)
) ;_ end strcat
) ;_ end setq
(if (caddr (nth pLen nlist))
(strcat wLine "," (rtos (caddr (nth pLen nlist)) 2 2))
) ;_ end if
) ;_ end while
(write-line (strcat pStr "\t" wLine) oFile)
) ;_ end progn
(princ "\n<!> No Line Name Specified. <!>")

Sorry, my mistake, initial post would only read first vertex.



(defun c:plco (/ File oFile pLin pStr nlist pLen wLine wfLine)
(if (setq File (getfiled "Create a Text File" "C:\\" "txt" 9))
(progn
(setq oFile (open file "W"))
(while (setq pLin (ssget ":S" (list (cons 0 "LWPOLYLINE") (cons 410 (getvar "CTAB")))))
(sssetfirst nil pLin)
(if (/= (setq pStr (getstring t "\nSpecify Name for Selected Polyline >> ")) "")
(progn (foreach x (entget (ssname pLin 0))
(if (eq 10 (car x))
(setq nlist (cons (cdr x) nlist))))
(setq nlist (reverse nlist) pLen (length nlist) wfLine "")
(while (not (minusp (setq pLen (1- pLen))))
(setq wLine (strcat (rtos (car (nth pLen nlist)) 2 2) ","
(rtos (cadr (nth pLen nlist)) 2 2)))
(if (caddr (nth pLen nlist))
(strcat wLine "," (rtos (caddr (nth pLen nlist)) 2 2)))
(setq wfLine (strcat wLine "\t" wfLine))
) ;_ end while
(write-line (strcat pStr "\t" wfLine) oFile)
) ;_ end progn
(princ "\n<!> No Line Name Specified. <!>")
) ;_ end if
(sssetfirst nil)
) ;_ end while
(close oFile)
) ;_ end progn
(princ "\n<!> No File Selected. <!> ")
) ;_ end if
(princ))

Lee,

It doesn't appear this code would work for "polylines"? I see they can be selected, but code seems to use just group code 10 for vertices (so works for 'lwpolylinwes'). To get vertices of a regular (heavyweight) polyline you'll need a different method, such as stepping through with 'entnext'. Seeing that the OP asked for z values as well, he might even want it to work for 3d polylines.

[Lee Mac]

Sorry Carl, will sort it.

[Lee Mac]

Ok, try this:



(defun c:plco (/ File oFile pLin pStr pEnt nlist pLen wLine wfLine vPt wvLine)
(if (setq File (getfiled "Create a Text File" "C:\\" "txt" 9))
(progn
(setq oFile (open file "W"))
(while (setq pLin (ssget ":S" (list (cons 0 "LWPOLYLINE,POLYLINE") (cons 410 (getvar "CTAB")))))
(sssetfirst nil pLin)
(if (/= (setq pStr (getstring t "\nSpecify Name for Selected Polyline >> ")) "")
(progn
(setq pEnt (ssname pLin 0))
(cond ((= "LWPOLYLINE" (cdr (assoc 0 (entget pEnt))))
(foreach x (entget pEnt)
(if (eq 10 (car x))
(setq nlist (cons (cdr x) nlist))
) ;_ end if
) ;_ end foreach
(setq nlist (reverse nlist)
pLen (length nlist)
wfLine ""
) ;_ end setq
(while (not (minusp (setq pLen (1- pLen))))
(setq wLine (strcat (rtos (car (nth pLen nlist)) 2 2)
","
(rtos (cadr (nth pLen nlist)) 2 2)
) ;_ end strcat
) ;_ end setq
(setq wfLine (strcat wLine "\t" wfLine))
) ;_ end while
(write-line (strcat pStr "\t" wfLine) oFile)
)
((= "POLYLINE" (cdr (assoc 0 (entget pEnt))))
(setq wvLine ""
pEnt (entnext pEnt)
) ;_ end setq
(while (/= (cdr (assoc 0 (entget pEnt))) "SEQEND")
(setq vPt (cdr (assoc 10 (entget pEnt)))
wvLine (strcat (rtos (car vPt) 2 2)
","
(rtos (cadr vPt) 2 2)
","
(rtos (caddr vPt) 2 2)
"\t"
wvLine
) ;_ end strcat
pEnt (entnext pEnt)
) ;_ end setq
) ;_ end while
(write-line (strcat pStr "\t" wvLine) oFile)
)
) ;_ end cond
) ;_ end progn
(princ "\n<!> No Line Name Specified. <!>")
) ;_ end if
(sssetfirst nil)
) ;_ end while
(close oFile)
) ;_ end progn
(princ "\n<!> No File Selected. <!> ")
) ;_ end if
(princ)
) ;_ end defun

thx Lee Mac, works perfect. This is what i need. thx again

[Lee Mac]

Excellent, glad it worked OK for you.

I had to mess around with it a bit to work with 3DPolylines, as I normally only work in 2D - but got it working in the end :P

[iztok13]

Lee mac:

sorry it doesnt work like a charm, i notice that if i had a lot of polilys , coordinates get in mess, basicly the first poly is OK then the second poly had 2 times more vertex, i try to corect this but i didnt succses.
any idea. & also if can be in front of coordinates the name of poly?

thx

[Lee Mac]

I'll have a look at it :)

[iztok13]

o that was fast replay, thx in advance so i have one more wish, if can be every vertex in one line.

if i have name of poly : vertex_name and x, y, coordinates

vertex_name x y
vertex_name x y
vertex_name x y
vertex_name x y

i hope u understand, & again thx in advance

[Lee Mac]

This is a quick fix for the multiple coordinate issue:



(defun c:plco (/ File oFile pLin pStr pEnt nlist pLen wLine wfLine vPt wvLine)
(if (setq File (getfiled "Create a Text File" "C:\\" "txt" 9))
(progn
(setq oFile (open file "W"))
(while (setq pLin (ssget "_:S" (list (cons 0 "LWPOLYLINE,POLYLINE") (cons 410 (getvar "CTAB")))))
(sssetfirst nil pLin)
(if (/= (setq pStr (getstring t "\nSpecify Name for Selected Polyline >> ")) "")
(progn
(setq pEnt (ssname pLin 0))
(cond ((= "LWPOLYLINE" (cdr (assoc 0 (entget pEnt))))
(foreach x (entget pEnt)
(if (eq 10 (car x))
(setq nlist (cons (cdr x) nlist))
) ;_ end if
) ;_ end foreach
(setq nlist (reverse nlist)
pLen (length nlist)
wfLine ""
) ;_ end setq
(while (not (minusp (setq pLen (1- pLen))))
(setq wLine (strcat (rtos (car (nth pLen nlist)) 2 2)
","
(rtos (cadr (nth pLen nlist)) 2 2)
) ;_ end strcat
) ;_ end setq
(setq wfLine (strcat wLine "\t" wfLine))
) ;_ end while
(write-line (strcat pStr "\t" wfLine) oFile)
(setq nlist nil
wfLine nil
)
)
((= "POLYLINE" (cdr (assoc 0 (entget pEnt))))
(setq wvLine ""
pEnt (entnext pEnt)
) ;_ end setq
(while (/= (cdr (assoc 0 (entget pEnt))) "SEQEND")
(setq vPt (cdr (assoc 10 (entget pEnt)))
wvLine (strcat (rtos (car vPt) 2 2)
","
(rtos (cadr vPt) 2 2)
","
(rtos (caddr vPt) 2 2)
"\t"
wvLine
) ;_ end strcat
pEnt (entnext pEnt)
) ;_ end setq
) ;_ end while
(write-line (strcat pStr "\t" wvLine) oFile)
(setq wvLine nil)
)
) ;_ end cond
) ;_ end progn
(princ "\n<!> No Line Name Specified. <!>")
) ;_ end if
(sssetfirst nil)
) ;_ end while
(close oFile)
) ;_ end progn
(princ "\n<!> No File Selected. <!> ")
) ;_ end if
(princ)
) ;_ end defun



But I may consider re-writing this LISP as I am not happy with it.

As for the other request - would you like the name of the polyline after all the coordinates?

[Lee Mac]

One more question -->

Will you only be working with POLYLINES (3D) or will I have to encompass LWPOLYLINES (2d) also?

[Lee Mac]

Ok, this is better I think:

Only works on POLYLINES for the minute, but if you need it expanded I shall write another.

Select as many POLYLINES as you like at a time :)

[iztok13]

A big thx for the effort.

But this is complitly different from the first one.
I will explain:

I have normal Polyline not 2d or 3d polys. All polylines are closed. Every single polyiline have a different name. So I need to be ask for each poly what is a name of it.

Basicly is somthing like the first lisp you wrote. It s workin only coordinates of the second, thrd ,.., are wrong or they are repeat. I dont now why?

Example, if I have four closed normal poly (not 2D or 3D) with name A,B,C and D. A have 4 vertices, B have 4 vertices, C have 7 vertices and D have 3 vertices, the TXT file should looks like that:


A x,y
A x,y
A x,y
A x,y
B x,y
B x,y
B x,y
B x,y
C x,y
C x,y
C x,y
C x,y
C x,y
C x,y
C x,y
D x,y
D x,y
D x,y

Here is a preview of example drawing:

[/URL][URL="http://img90.imageshack.us/my.php?image=polylinesso4.jpg"]http://img90.imageshack.us/img90/8498/polylinesso4.th.jpg (http://img90.imageshack.us/my.php?image=polylinesso4.jpg)

A,B,C,D are the name of polys, x and y are coordinates of them.

I hope i dont make a lot of trouble for this..

Thx in advance..:oops:

[Lee Mac]

Did my other posted LISP not fix the multiple co-ordinate issue?

[iztok13]

I didnt try on 3d or 2d polyline, only on normal polyline, when i select the polyline it say nothing selected????

Mybe because is not 2 or 3D poly??

[Lee Mac]

Is can only be a 2D or 3D poly - unless you are working in 4D which I highly doubt... :wink:

I am surprised it says nothing selected... could you post a sample drawing in 2000 format that I could work from?

[iztok13]

ok, thx
here is an example of my drawing of polylines:

http://www.2shared.com/file/4743843/d6e1e7a4/polylines.html

thx

Name of polyline is like this :"SEM-S3-10"......

[Lee Mac]

Ok,

Please look at the documents attached and verify that the notepad doc "desired" is what you wish:

Then the above should do your bidding. :)

[iztok13]

ok the the desire file is ok, But when i run plco2 lisp writen above i cant select poly, it say nothing selected????

please try the file wich i upload and try if you have the same problem?

[Lee Mac]

I can't get to the file you uploaded...

Can you not attach the file?

[iztok13]

Ok here is the same file;

9811

:)

[Lee Mac]

Ahh, you are using (2D) LWPolylines - I shall alter the LISP accordingly :)

[Lee Mac]

Here you are - just window the whole drawing to select polylines (as in your example).
