  1. I have been trying to figure this out for a couple of days now. The only thing I could find is this LISP that takes the Ellipse properties and uses them to creat an arc. When I use this, the start and end angles are not correct in the drawing. Ellipses must have been drawn in a different UCS). I have tried to get the LISP to use the start and end points of the ellipse along with the radius and center point. For the life of me I cannot figure it out. If anyone knows how to do this please let me know. *NOTE* Elllipses that I am trying to convert have the same minor and major radii. Thanks in advance!!

  2. Hello, I need to join an ellipse to a circle then trim the ellipse but keep the whole thing joined. I know how to trim. But I can not join the trimmed to the circle. HELP!!!! Richard
  3. Hi CADmates, how is it possible to recognize an ellipse object is closed (i.e. full ellipse) or open (i.e ellipse arc)? Any reply appreciated.
