boundary objects?

[Anonymous]

When creating a boundary by using the boundary command and picking an
internal point, is it possible to determine the entities the boundary uses
as the outer edges?

Thanks again!

As far as I know, it uses a selection from all the objects visible on the screen.

Devitq found trhat attached is working wrong
Sorry for that
Try this insted it will return the selection set of
parent edges I hope
I can't to test it extensively, try it by your self

(defun getedges (/ )
(vl-load-com)
(setq pt (getpoint "\nPick internal point: "))
(command "._-boundary" pt "")
(setq boundary (entlast))
(setq obj (vlax-ename->vla-object boundary))
(setq len (vlax-curve-getdistatparam obj (vlax-curve-getendparam obj)))

(setq div 1024); number of division
(setq step (/ len div)
dis step
)
(repeat div
(setq pt (vlax-curve-getpointatdist obj dis)
pt_list (cons pt pt_list)
dis (+ step dis)
)
)
(setq ss (ssget "F" pt_list))
(ssdel boundary ss)
ss
) Do not use attached lisp routine

Sure - in the dialog box the lowest section says boundary set which defaults to the display with a New button - via
which you can select the objects form which the boundary may be determined - make your selection, , then pick
your point.

Thanks, does that routine return the original entities, or the entities
created as part of the new boundary polyline?

Thanks, Bob

The new boundary - not those objects that could form a closed area.
