Points to Circles

[vijaybaskergundla]

Hello,

I am having 1000's of points in Auto cad File.

I want to convert these all points to cirlces with single command.Anybody can help me if you know or having lisp file at your side.If you provide this file I may be save lot of time.

Thanks,
Vijay

Are they actual autocad "points"?
Do you want actual circles or just have them appear as circles?

If you want them to just appear as circles, change the variable PDMODE to 32 or 33.
And then do a "REGENALL"
(look into the variables DDPTYPE, PDMODE and PDSIZE)



If you want actual circles, maybe someone has a lisp routine, (it sounds do-able).

are the points a block that contain a point? if so, you could redefine the block.

Here is a quick stab at it...

(setq sset (ssget "_X" '((0 . "POINT"))) i 0)
(if sset
  (repeat (sslength sset)    
    (setq ent (ssname sset i))
    (entmake
      (list
        (cons 0 "CIRCLE")
        (cons 10 (cdr (assoc 10 (entget ent))))
        (cons 40 10.0) ;circle size, change the 10.0 to whatever you want
      )
    )
    (entdel ent)
    (setq i (1+ i))
  )
)

Hi,

You can see this 'challenge' at the TheSwamp, there was many replys in many prog languages.

Thanks a LOT,It is working and useful to us.

But can u give it as in lisp file,Actually I copied this code and pasted in Auto cad command prompt,all points are changed to circles,its OK.Instead of that If I use with command,it may be very convent,So If it is possible Can u give me with Lisp DEFUN CODE.

Thanks,
Vijay

      )
    )
    (entdel ent)

To erase all points in the selection set after the repeat loop, reduce the time with more than 40 % compared to erase all points one by one in the repeat loop.

Obviously, there are many ways to reduce the process time... as evidenced by the thread over in the swamp (referenced above...). In most cases, unless you are operating on hundreds of thousands of entities, the time spend to optimize such code is much greater than what would be saved...

yes, that is true . . .

(entdel ent) or (command "._erase" sset "" )
