I think I have resolved your wishes. However, I noticed for example that for a polyline with overlapping vertex, the new entity is not created. Use OVERKILL on any that might cause problems. foo.lsp

Do you know much about lisp ? 1st returns 8 entities in your dwg as you have before and after remove "X" if you want to select dwg area objects. (setq ss (ssget "X" '((0 . "LWPOLYLINE")(cons 8 "ss-bor")(cons 410 (getvar 'ctab))))) Loop through ss and get co-ordinates of each rectang. (if plent (setq co-ord (mapcar 'cdr (vl-remove-if-not '(lambda (x) (= (car x) 10)) (entget (car plent)))))) Then get the text with another ssget, it should only get 1 then retrieve Text string (setq ss2 (ssget "CP" co-ords '((0 . "TEXT")"(cons 8 "ss-pre")(cons 410 (getvar 'ctab))))) Then get line work (setq ss3 (ssget "CP" co-ords '((0 . "*LINE")"(cons 8 "ss-part")(cons 410 (getvar 'ctab))))) Then make block using ss3. Continue looping till end. This is just sequence not a full program.

1st (command "rectangle" pt1 pt2) 2nd you need to look at objects as get vertices for plines, endpoints for lines, center point circle, start & end & center point for arc. (cond ((= arc ((= circle ((= Line ((= lwpolyline ) 3rd for pline (setq plent (entsel "\nPick rectang")) (if plent (setq co-ord (mapcar 'cdr (vl-remove-if-not '(lambda (x) (= (car x) 10)) (entget (car plent)))))) (princ co-ord) What do you want to do with the points ask now rather than later.

I use this lisp routine, courtesy of Kent Cooper. ;; CirclePolylineSwap.lsp [command names: C2P & P2C] ;; Two commands, to convert in both directions between a Circle and a circular ;; (two-equal-arc-segment closed) Polyline, such as the Donut command makes. ;; Both commands: ;; 1. ask User to select again if they miss, pick an incorrect object type, or pick an ;; object on a locked Layer; ;; 2. remove selected/converted object, but can easily be edited to retain it; ;; 3. account for different Coordinate Systems; ;; 4. retain non-default/non-Bylayer color, linetype, linetype scale, lineweight, ;; and/or thickness. ;; See additional notes above each command's definition. ;; Kent Cooper, May 2011 ;; C2P ;; To convert a selected Circle to a two-equal-arc-segment closed zero- ;; width Polyline circle [Donut w/ equal inside & outside diameters], ;; which can then be modified as desired [given width, etc.], since Pedit ;; will not accept selection of a Circle. ; (defun C:C2P (/ *error* cmde csel cir cdata cctr crad cextdir pdata) (vl-load-com) (defun *error* (errmsg) (if (not (wcmatch errmsg "Function cancelled,quit / exit abort,console break")) (princ (strcat "\nError: " errmsg)) ); end if (command "_.undo" "_end") (setvar 'cmdecho cmde) ); end defun - *error* (setq cmde (getvar 'cmdecho)) (setvar 'cmdecho 0) (command "_.undo" "_begin") (prompt "\nTo convert a Circle to its Polyline equivalent,") (while (not (and (setq csel (ssget ":S" '((0 .

One way would be to run the POLYGON command, set the number of sides to a high number like 500, then draw this on top of the existing circle, then erase the circle. This could be automated with autolisp if you were doing many of these. Something like this (quick and dirty, no error checking) (defun c:foo ( / CEN I K RAD SSET W ) (vl-cmdf "._layer" "_m" "polylines" "_c" "40" "polylines" "") (setq sset (ssget "_X" '((0 . "CIRCLE"))) i 0) (repeat (sslength sset) (setq k (ssname sset i)) (setq w (entget k)) (setq rad (cdr (assoc 40 w))) (setq cen (cdr (assoc 10 w))) (vl-cmdf "._polygon" "500" cen "_C" rad) (entdel k) (setq i (1+ i)) ) )
