Topic: PLINE JOIN

[TJAM51]

I am seeking a routine that will join a pline and offer a crossing or pick without having to go throuh all the PEDIT process....thanks

If you have express tools use pljoin

I have this but never tried it.

Code: [Select]

;;  from Marc'Antonio Alessi (nospam_maalessi_at_tin_dot_it)
; #PlineJoinPrec = global
;
(defun C:ALE_PlJoin (/ SelSet FltLst OldLPr)
 ;(setvar "CMDECHO" 0) ; I have always = 0
  (princ "\nSelect lines, arcs or polylines to join:  ")
  (setq OldLPr (getvar "LUPREC"))  (setvar "LUPREC" 8)
  (setq
    FltLst
    '((0 . "LWPOLYLINE,POLYLINE,LINE,ARC"))
    #PlineJoinPrec
     (ureal 5 "" "Precision distance" (cond ( #PlineJoinPrec ) ( 0.00001 )))
  )
  (setvar "LUPREC" OldLPr)
  (cond
    ( (not (setq SelSet (cond ((ssget "_I" FltLst)) ((ssget FltLst)))))
      (prompt "\nNo arc or polyline selected.  ")
    )
    ( (ssget "_P" '((0 . "LINE,ARC")))
      (command "_.PEDIT" "_M" SelSet "" "_Y" "_J" "_J" "_E" #PlineJoinPrec"")
      (princ (strcat

HOW CAN THIS ROUTINE BE REWRITTEN SO THAT IT IS NOT NECESSARY TO ENTER FUZZ DISTANCE AT THE COMMAND LINE EACH TIME, BUT THE OPTION COULD BE AVAILABLE?

[Mark]

If you have a few dollars and don't want to write you own .... GBPoly [ http://www.geometricad.com/ ] You'll find it hard to beat.

[DanB]

Here's the one I use...

Code: [Select]

;;
;; 06/22/05
;; Polyline Joins Selected Objects
;;
  (defun c:j (/ ss)
   (prompt "\nSelect Objects to Join... ")
   (setq ss (ssget))
   (command "pedit" "m" ss "" "j" "" "")
   (princ)
  )

Very good app.

[LE]

Yes....

Here is a link to see GBPOLY in action:

http://www.geometricad.com/app.php?id=1&lang=en

There are a lot of open source, samples on how to join plines, lines and arcs, if you are looking for a smart and easy way to generate closed areas, then give GBPOLY a try.

[SMOKIIBEAR]

Ahhh...that makes me happy

Thanks.  One of these days, I need to starting writing lisp.

Ditto.

[whdjr]

I think that was invitation only forum.  You had to sign up for the class.

Maybe Mark can unlock that for everyone?

edit
Sorry 'bout that guys I forgot.

[Keith™]

I get the same thing .... perhaps when Mark was playing around with the board he got it mal-adjusted ...

[jonesy]

That was a course that was run by Stig. We had to sign up for the course. I believe its only for the students on Stigs course.

However I just remembered about This

I havent tried it myself yet, so I'm not sure about its content.

Happy reading.

I just got both links but I was signed up.
Or perhaps Mark changed something.

I am seeking a routine that will join a pline and offer a crossing or pick without having to go throuh all the PEDIT process....thanks

some info is missing here...
if you have 2 PLINEs or LINEs...
but in diffrent color and/or linetype....

How can you detect wich you need to joint ??

eg: you have a RED pline and a BLUE LINE...
you need to joint both..

but, need to take the BLUE layer...or color...or linetype...
if after making...you result was RED in wrong layer...
you do not have saved much time... and even worse.

isn't it ?

so that why i think crossing option is not good idea.  :kewl:

[whdjr]

The one you pick first should be the dominent line.  If you pick blue then red then the new line will be blue.

[Andrea]

Ok, I have wrote this..few year ago..
maybe the syntax is not perfect..but you can verify and modify as your own..

Code: [Select]
