Thanks for the tip, Alessandro. It will help in a pinch, but it would still be nice to manipulate the ellipse directly, and not wind up with dozens of little snippets.Roy On Jan 2, 2015, at 4:50 PM, 'ing. Alessandro PETRUZZI'

I would especially like to use the ellipse as a cutting edge and to be able to trim the ellipse.Hear, hear! I first raised the inconsistency of the ellipse tool with Thorsten on 18 August 2003 and have been hoping ever since that it might be made to behave like the circle and arc tools do for trimming, and for delimiting areas for hatching etc. It’s also annoying that starting and ending angles for elliptical arcs cannot be defined correctly. (Try creating circular & elliptical arcs subtending the same angles from the same centre to see what I mean.)in friendshipRowland: Rowland Carson ... that's Rowland with a 'w' ...: <
