Shibuboss Posted September 10, 2009 Posted September 10, 2009 Hello everybody, How can i get the radius of an " ELLIPSE". The method i used :- 1.Set PELLIPSE=1 2.Draw the Elipse 3.Explode the Ellipse 4.Get Arc or Spline -Not sure. Is the correct method to find Ellipse's radius? Is there is any Lisp routine/other commands in Autocad? Please advise.thank you. Regards_______ Quote
fuccaro Posted September 10, 2009 Posted September 10, 2009 The true ellipse's radius differs in each point. When PELLIPSE is set to 1, it approximates the ellipse with small arcs. The arcs having constant radius, they introduces errors so they are small to keep the errors small. You can get the radius of each arc -and that is around the real radius of the ellipse in that point. Quote
