Moving objects within polyline to different layer

[Hsanon]

Hi, Is there a Lisp routine which can move all objects within a selected polyline to a layer called "exist" and all objects outside that same polyline to a layer called "site" ?? ignoring all frozen or OFF layers ?? Regards.

If you want to have a go, look at Selection Sets to select everything within the polyline (see Lee Mac Selection sets page - it is rather good - ssget), window polygon or crossing polygon

Do 2 selection sets - one for everything "_X" and one for Crossing Polygon, I think Lee Mac has a routine there to remove one selection set from another.

This gives you 2 sets of entities to work with

Loads of LISPs out there to change layers.

 

Have a go, it is easier than you might think

Try this:

(defun c:chglyobjpl (/ acdoc p_list p_coord sset ent obj newLayerName i)

  (vl-load-com)
  (setq acdoc (vla-get-ActiveDocument (vlax-get-acad-object)))

  (setq p_list (entget (car (entsel "\nSelect the LwPolyline: "))))

  (if (setq
        p_coord (mapcar 'cdr
                        (vl-remove-if-not '(lambda (x) (= (car x) 10)) p_list)
                );;end setq p_coord
      );;end if condition
    (sssetfirst nil (setq sset (ssget "_wp" p_coord)))
  )
