I have a lisp that copies everything inside a circle, but I wish I can copy everything inside a closed polyline. Can you help me editing this code? (defun c:det (/ osm blip ent alist cir1 pt1 raio1 cir2 pt2 raio2 fator ss pt) (setq p1 (getpoint "\nSelecione o raio do círculo de ampliação:")) (command "CIRCLE" p1 pause "") (command "undo" "be") (setq osm (getvar "osmode")) (setq blip (getvar "blipmode")) (setvar "blipmode" 0) (setvar "osmode" 0) (setvar "cmdecho" 1) (while (not cir1) (setq ent (car (entsel "\nSelecione o círuculo a ampliar: "))) (if (and ent (setq alist (entget ent)) (= (cdr (assoc 0 alist)) "CIRCLE") ) (setq cir1 ent pt1 (cdr (assoc 10 alist)) raio1 (cdr (assoc 40 alist)) ) ) ) (command "copy" cir1 "" pt1 pause) (setq cir2 (entlast) alist (entget cir2) pt2 (cdr (assoc 10 alist)) ) (command "scale" cir2 "" pt2 pause) (setvar "cmdecho" 0) (setq alist (entget cir2) raio2 (cdr (assoc 40 alist)) fator (/ raio2 raio1) ) (command "copy" "cp" (foreach pt (pt_circulo pt1 raio1 T) (command pt) "" ) "r" cir1 "" pt1 pt1 ) (setq ss (ssget "p")) (command "move" ss "" pt1 pt2) (command "scale" ss "" pt2 fator) (repeat 2 (command "trim" cir2 "" "f" (foreach pt (pt_circulo pt2 raio2 nil) (command pt) "" ) "" ) ) (setvar "blipmode" blip) (setvar "osmode" osm) (setvar "cmdecho" 1) (command "undo" "e") (princ) ) (defun pt_circulo (centro raio inscrito / ang ndiv delta pt resp) (setq ang 0 ndiv 36 delta (dtor (/ 360 ndiv)) ) (if (not inscrito) (setq raio (* 1.0001 (/ raio (cos (/ delta 2.0))))) ) (repeat (1+ ndiv) (setq ang (+ ang delta)) (setq pt (polar centro ang raio)) (setq resp (append resp (list pt))) ) ) (defun dtor (a) (* pi (/ a 180.00)) ) (princ)

Hi guys, Does anyone know know can i scale a 2D object to an exact length and width that i need to fit into a space? Ive been reading around online and they say use scale/ref, however i noticed by giving the ref length, it does lengthen the object to the ref length, but the height's off!! Thanks

Hi, I am new to AutoCAD and I want to draw something in it, I have taken screen shot of a google map and placed it in AutoCAD, Now I want this map to be scaled proper size, for example I have 880meter x 330meters but placed object is only 20' x 15'. How can I resize it or how can I make my drawn line to be exact 880meters ? ( I will resize my picture according to my drawn line).
