how to check break point along a polyline

[Anonymous]

I want to circle them up

[Vinayv4v]

Hi,

Here is a Lisp From Kent Cooper for circling break points along lines

(defun c:cmark (/ crad ss ln)
(Command "ucs" "World")
(setq
crad (getdist "\nSpecify radius: ")
ss (ssget "X" '((0 . "LINE")))
)
(repeat (sslength ss)
(setq ln (entget (ssname ss 0)))
(command
"_.circle"
(cdr (assoc 10 ln))
crad
"_.circle"
(cdr (assoc 11 ln))
crad
)
(ssdel (ssname ss 0) ss)
)
(Command "ucs" "p")
)

You need a little bit of modification to try this on polylines.

If you mean what most people call the vertices of Polylines, this routine places Points at all of them [you can set the PDMODE System Variable to make the Points visible in whatever style you prefer], and could easily be adjusted to draw circles, if you need that specifically.
