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?

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

| 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. |

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. https://knowledge.autodesk.com/support/autocad/learn-explore/caas/sfdcarticles/sfdcarticles/Change-true-ellipse-into-polyline.html  |

[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.]
