Replace objects with Blocks?
« on: December 05, 2007, 08:20:59 AM »
Do you guys think it would be a possibility to write a tool to replace an object with a block or do you think there are too many unknowns?  I need to do this in a couple hundred places.

My dilemma is I have a dwg with a bunch of rectangles as door threshholds.  I need to add a note to these rect's but I already have a threshhold block with a note in it.  I wanted to get you guy's feedback as to whether you thought it possible to code this or just too many variables.

I believe it would be a matter of selecting all rectangles, choosing an insertion point from the given rectangles point list (or if you want to use the center of each rectangle as your insertion point, use polar to find it), then insert each block instance into that space, using one of the various looping calls and finally deleting (if that's what you want) the selection set of rectangles. That sounds like between 4-8 variables. Not too many.

Right off the top of my head I'd say there are too many unknowns.   Maybe a dynamic block with an alignment parameter would be faster/easier?

Daron's idea sounds pretty good... Are all of the threshholds the same size?

Yes the thresholds are all the same size however some have a rotation of 0 and some 90.  The block I intend to insert is Dynamic but it doesn't have an alignment parameter.  I'll put something together and see what I come up with.

Thanks

So, you're replacing one rectangle for another of the same size? All you have to do to get the angle of point1 and point4. If your block is set up where the rectangle is horizontal, set the insertion point in the block the middle of the rectangle. If there happens to be a block that is rotated 90 from what it should be, have a function created that will rotate it 90 degrees. However, dynablocks are good too.

I would think it would be a relatively easy task.
The rectangles to be replaced are on  specific layer or maybe two. The rectangles are a specific size
or at least a specific length with a limited range of widths. So selecting them would be a two step
process. Scaleing the block & rotating it shouldn't be a problem.

The biggest problem would be to insert the block at the correct rotation as it would be different if the original rectangle were drawn clockwise or counterclockwise.

Something like this could be used.
Note that this is just the start & not a complete solution.

Code: [Select]
(defun c:test()
  (defun rtd (r) (* 180.0 (/ r pi)))
  (setq rec (car(entsel "\nPick Rectangle.")))
  (setq elst (entget rec))
  (setq vlst (mapcar 'cdr (vl-remove-if-not '(lambda (x) (= 10 (car x))) elst)))
  (setq s1 (distance (car vlst) (cadr vlst))
        s2 (distance (car vlst) (last vlst)))
  (if (> s1 s2)
    (setq ang (angle (car vlst) (cadr vlst)))
    (setq ang (angle (car vlst) (last vlst)))
  )
  (if (and (> ang (* 0.5 pi)) (< ang (* 1.5 pi)))  ;flop text at >90 and <270
   (setq ang (+ ang pi))
  )
  ang
)

Kinda *crude but wouldn't something like this:

(defun c:test()
  (defun rtd (r) (* 180.0 (/ r pi)))
     (setq cnt 0)
     (setq ss (ssget "x" (list '(8 . "0") '(0 . "LWPOLYLINE"))))
     (repeat (sslength ss)
  (setq elst (entget (ssname ss cnt)))
  (setq vlst (mapcar 'cdr (vl-remove-if-not '(lambda (x) (= 10 (car x))) elst)))

   (setq ang (+ ang pi))
  )
(setq cnt (1+ cnt))
)
  ang
)
aleviate the pain of having to hand select each rectangle?

*crude because I just took CAB's code and made it repeat from a selection set and didn't test it or anything.

Kewl! New toy!

I wonder how AEC walls and other so called "Smart Objects" will affect its selection.

I'll have to play with this.

Thanks for the code VVA, but it does match rotation and it doesn't put it in the same location.  It's off by a little bit, maybe a foot or so.
