Replace circle by block

Hi friends,

Is there any lisp to replace selected circles by block............

pls help me

Thanks

Try it

;;; Command changes the set of primitives for the selected primitive. 
;;; Examples: 
;;; Replacement of some other blocks. 
;;; Replacement blocks or dots circles. 
;;; Replacement of some other titles. 
;;; 
;;; First you need to select a sample, and then specify replaceable objects.
;;; Box is in the center is restricted (bounding) rectangle of old objects.
;;; New objects are inserted into the layers that Belonged to which the old objects. 
;;; Supports pre-selection.

First select block, then select circles

Thanks VVA and LEE

Both of the codes working nice.....it will help me lot.........

Thanking you

You're very welcome Mani

Hi Lee,

just wondering how you would change this to replace donuts?

I tried modifing the code, but cant get it to work properly.

Thanks

Steve

Donut isn't a type of entity; the DONUT command will generate thick polylines made by two arcs. So, you need to design an algorithm to recognize them. Will have to validate that the arcs share the same center point, were connected at ends and their inside angles were 180 degrees (DXF code 42 is set to 1.0 - this ensure also that the arcs were parsed in the same sense, so were not coincident).

You can covert donuts to circles via Express Tools - overkill.

Then run Lee's code.

Or try this to replace donuts:

(defun C:TEST ( / ss b)
 (and
   (setq ss (ssget '((0 . "LWPOLYLINE") (90 . 2) (70 . 1))))
   (setq b (getstring "\nBlock name: "))
   (tblsearch "BLOCK" b)
   (donut->block ss b)
   )
 (princ)
 )


(defun donut->block (ss b / i e r l p)
 (repeat
   (setq i (sslength ss))
    (setq e (entget (ssname ss (setq i (1- i))))
          r (mapcar 'cdr (vl-remove-if '(lambda (x) (/= (car x) 42)) e))
          )
    (if
      (or
       (equal r '( 1.0  1.0) 1e-10)
       (equal r '(-1.0 -1.0) 1e-10)
       )
      (progn
        (setq l (mapcar 'cdr (vl-remove-if '(lambda (x) (/= (car x) 10)) e))
              p (list (* 0.5 (+ (caar l) (caadr l)))
                      (* 0.5 (+ (cadar l) (cadadr l)))
                      (cdr (assoc 38 e))
                )
        )
        (entmake
          (list
           '(0 . "INSERT")
            (cons 2 b)
            (cons 10 p)
            (assoc 210 e)
            )
          )
        (entdel (cdr (assoc -1 e)))
      )
    )
  )
 (princ)
)

Thanks very much Stefan, that works fantastic!

Cheers

You are welcome Steve. I'm glad you like it.

Hi All,

I am new to this forum. I have been looking for a lisp routine that could select all circles of a specific diameter not a range or greater than/ less than scenario on any layer and replace them with a block reference then delete the original circle. Lee's code works well however i want to do a bulk selection and replacement not select each individual circle to be replaced. A counter to display how many circles have been replaced would be beneficial however not necessary. Can anyone help me?

stretch5544 if you look at the code above

(setq ss (ssget "_:L" '((0 . "CIRCLE")))) this selects a circle

(ssget "X" '((0 . "CIRCLE")))) will look through out the dwg and find all circles

(setq ss (ssget "X" '((0 . "CIRCLE")(cons 40 rad)))) will get all circles with a radius of rad

Start with lee's code above

Thanks BIGAL and Lee. Much appreciated. I will try that today and let you know how it goes.
