Break command in Lisp

Hi

I do not know why the command BREAK does not accept the first point of

it as "_f" in Autolisp as shown below ?

(command "_.break" objects "_F" .....

it brings Invalid point. ????

Any ideas ?

Regards

Use it like this:

(command "_BREAK" MyEntity MyPoint [color=red]"@"[/color])

Regards,

Thanks

And the following is hanging .

(setq abc (entget (ssname objs a)))
     (command "_.break" objs (cdr(assoc 50 abc)) "" "@" 20)

Regards,

The first argument should be an entity, not a selection set. Also, not sure about that 50 DXF code – what kind of entity you are using? Please see my example below to understand how it works:

(setq MyEntity (car (entsel)))   ;select a line
(setq MyPoint (getpoint))        ;select a point on that line (with Nearest)
(command "_BREAK" MyEntity MyPoint "@")

Regards,

Thank you .

My lisp is looping .

(if (setq objs (ssget "_x" '((0 . "CIRCLE,ARC"))))
(progn
 (setq i 0
       all (sslength objs))
   (while (< i all)
     (setq abc (entget (ssname objs i)))
     (command "_.break" abc (cdr(assoc 10 abc)) "@" [color="red"]45[/color])[color="red"]<---- in red to be cut from entities[/color]
     (setq i (1+ i))
( .........

You’re welcome!

Saw that your selection allow for circle selection, too - but you cannot break a circle entity using single point – arcs of 360 degrees aren’t supported in AutoCAD.

Hi

Why can't I break a circle since that I can break it in Autocad ?

Arcs are open not closed .

Thanks

At least up to AutoCAD 2010 (the last version that I ca test) you cannot break a circle using a single point – you will receive the below message:

Arc cannot be full 360 degrees

Regards,

I am working on Autocad 2009.

Please try the following in sequence in Autocad

command line: break

select arc

f

20

No messages at all

Thanks
