Adding vertices to a pline using another PLine as a template?
« on: March 06, 2009, 10:56:50 AM »
Can Pline vertices be added to a PLine using another pline vertices as a template?  That is the question.

The picture explains a lot so see the picture.  :evil: :-)  Currently I am adding the veritices ( with a lisp but then I have move the vertices  to break line's vertices.  I have to do this a lot so I was hoping that lisp could speed this up.

Why not use this?

See Twisted 8-)

The picker option is what I need but it would not modify the green line.  It would modish the break line as described but that is not the one that I needed.   It is faster because it as adding and stretching at the same time.   I will post in the thread and see if Andrea knows what is up.  I will say that the rectangle was modified by ADT tools and the object is closed pline.  It probably the ADT modifications that is causing it to hick up.

Thanks CAB.

It looks like I can not use DLMO because not being able to use osnaps.  IT is pretty cool routine.  :-)

It would be helpful if you can post a sample drawing, so others would know what would be the most appropriate method to tackle the problem. Are your break lines LINEs or LWPOLYLINEs. If they are LINEs, I'd join them first into LWPOLYLINEs. I think that will simplify the programming. I'm only thinking how I would do it.

krushert,
This routine doesn't work for you?
Or you are looking for less picks?

CAB, I am checking from home and don't have cad installed here.  I will check on Monday with this Rountine.

I will post a dwg on Monday.  What I want to do is is Pick the PLINE then I want to add vertices to and then select the break line to be use as a template.   Then let the routine to analize the breakpoint pline to find it's vertices and then add vertice to the to the first selected pline where the breakline vertices are.

Thanks Guys and type at on Monday unless I have to repath all my users machines because of incomptant IT Contractor.   :ugly:

I think you will need a specialized routine if you want a two pick solution.  :roll:

With the Gile's routine, I think I used 8 picks to get the results you wanted.

I actually am using RonJonp's routine that started that thread.  :-D  I am doing it 8 picks and/or moves.  4 moves to add the vertices and then 4 moves to grip stretch which is probably 2 picks per stretch.  Lets see 12 details per sheet and with (lets say) 2 breaks per detail on the average .... you get the picture.

I am going to try it with Gile's routine this afternoon.  I will get back to you. Thanks.

And that saves me 2 picks becuase I can use Osnaps for two vertices.  Thus I only need to grip stretch 2 points. 
Cool.  Every little helps.  Thanks CAB.

WHOOAA!!!!   :-o :-o
This is what I needed.  I did not realize that I could drag/place the vertex "outside"  the pline.   4 picks, thank you very much.
Very Cool. Thanks Guys.   Sorry I did not clue into to it sooner.  :oops:
 :-D :-D

Try this one....still needs alot of work (error checking)...but should do what you want in 1 pick. :-P

Code: [Select]
(defun c:breakitmeng (/ ang ds e n obj param pt pt1 pt2 pt3 pt4 width height)
  (vl-load-com)
  (if (zerop (setq ds (getvar 'dimscale)))
    (setq ds 1.0)
  )
  (if (and (setq e (entsel "\Select polyline: "))
           (setq pt (cadr e))
           (setq e (car e))
           (= (cdr (assoc 0 (entget e))) "LWPOLYLINE")
           (setq obj (vlax-ename->vla-object e))
           (setq pt (vlax-curve-getclosestpointto e pt))
           (setq param (fix (vlax-curve-getparamatpoint e pt)))
           (setq ang (angle (vlax-curve-getpointatparam e param)
                            (vlax-curve-getpointatparam e (1+ param))
                     )
           )
           (setq width (* ds 0.35))
           (setq height (* ds 0.7))
           (setq pt1 (polar pt (+ pi ang) width))
           (setq pt2 (polar pt1 (+ (angtof "67.5") ang) height))
           (setq pt3 (polar pt ang width))
           (setq pt4 (polar pt3 (+ (angtof "247.5") ang) height))
           (setq n 0)
      )
    (foreach pt (list pt1 pt2 pt4 pt3)
      (setq n (1+ n))
      (vlax-invoke obj 'addvertex (+ param n) (reverse (cdr (reverse pt))))
    )
  )
  (princ)
)
(c:breakitmeng)

breakitmeng is pretty slick.

Cool.  But alas it not what "Exactly" need.

Let me Zoom out a little and I post a bigger picture.  I use the express tools break line to go across a series of objects.  usually the center object get vertices added to it but not always.  Hence my question about using another pline as template
