[PELLIPSE is a System Variable, not a command like PEDIT.  It will affect whether newly-drawn Ellipses are true Ellipse objects or Polyline approximations.  Not being a command, it can't convert an existing Ellipse object into a Polyline, which is the original request here.  Also, with PELLIPSE=1 you don't get a choice of number of arc segments in the approximation -- it's always 16, and there is no option to draw a partial Ellipse, so if you want that, you need to draw the full one and Trim or Break it.]

Hello CadClothier and Kent, oups I did it again, in fact it's PELLIPSE...
I think that you have to choose a number of points for your polyline, do not choose a too high number.

PEDIT doesn't accept selection of an Ellipse [as of Acad2020 that I have here].  One thing you can do is to OFFSET it outward, resulting in a Spline, then Offset that again inward by the same amount, resulting in a Spline overlaying the Ellipse, which you can then work on with PEDIT.]]> Wed, 12 Oct 2022 20:32:33 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=13766&PID=38421&title=not-a-polyline-no-prompt#38421 <![CDATA[Not a Polyline no Prompt : Try the PEDIT command ( Polyline...]]> https://www.cadforum.cz/forum_en/forum_posts.asp?TID=13766&PID=38419&title=not-a-polyline-no-prompt#38419 Author: philippe JOSEPH

Try the PEDIT command ( Polyline EDIT ) and follow the instructions ( options to take ) on the command line ( eventually press F2 to see better ).

Hi all,

I am trying to convert a shortened ellipsis (looks like an arc now) to a polyline to connect to other polylines. However, selecting gives the note "this object is not a polyline" without the prompt to change it to one. Is there a fix for this?
