add elips in polyline

ellipse is actually a spline. you must trace over it with polylines or arcs.. I use divide and set my spaces pretty close then set my Osnap on node & go. HTH Rob

You can't use a true ellipse. Instead, set PELLIPSE to 1 to force AutoCAD to approximate your ellipse with a polyline; you can then trim, PEDIT, etc. to your heart's content. ___

Try to use boundary. Draw the ellipse, draw your pline, than make a new boundary and it wil create a region. It's not a polyline but if you need it for hatching it works.

It's impossible join an elips with a polyline but I have a lisp command that convert a spline into a lwpolyline... The name is CONVSPL

syntax: (load "convspl") CONVSPL

(defun C:CONVSPL (/ gru index index2 color ltype P0 nspline ent lisent) (setvar "CMDECHO" 0) (setq gru (ssget) index 0 nspline 0 ) (repeat (sslength gru) (setq ent(ssname gru index)) (if (= (cdr(assoc 0 (entget ent))) "SPLINE") (progn (command "SPLINEDIT" ent "REFINE" "E" 20 "X" "X") (setq lisent(entget ent) color(cdr(assoc 62 lisent)) ltype(cdr(assoc 6 lisent)) index2 0 P0(cdr(assoc 10 lisent)) ) (command "LAYER" "SET" (cdr(assoc 8 lisent)) "")(command "PLINE" (trans P0 0 1) )

(repeat (length lisent) (if (= (car(nth index2 lisent)) 10) (command (trans (cdr(nth index2 lisent)) 0 1) ) ) (setq index2(1+ index2)) )

(command) (if (/= color nil) (command "_CHPROP" (entlast) "" "COLOR" color "") )

(if (/= ltype nil) (command "_CHPROP" (entlast) "" "LTYPE" ltype "") ) (entdel ent) (setq nspline(1+ nspline)) ) ) (setq index(1+ index)) ) (princ "\nConvertite ")(princ nspline)(princ " spline.")(princ) )

Thanks you all. I'll try it out!

I'm a little confused, how do you use this?

I copeid the bit after "(defun...." into notepad and saved it of as an *.lsp I loaded the lsp into acadwin.

I type convspl at the command line, it promtps me to select something, which I do (an ellipse) it I press enter and it exits the routine. Nothing has happened. What am I doing wrong?

The LISP "convspl" converts a spline into a polyline. It can not be used to convert an ellipse into a pline.

Wouldn't it be easier to follow Pauls suggestion and draw the ellipse while PELLIPSE = 1? So you get a pline and can join it to other lines/polylines/arcs.
