Ellipse to Arc
|View HTML Version||Ellipse2ArcV1-1.html|
Although a somewhat obscure program since Ellipses & Arcs are geometrically incompatible (unless the Ellipse has axes of equal length), this appears to be a relatively common request across the AutoCAD community, and so I thought I'd share a program to perform the task.
This program will allow the user to convert a selection of circular Ellipses & Elliptical Arcs (that is, Ellipses or Elliptical Arcs with axes of equal length) into Circles & Arcs respectively, whilst retaining all properties of the original objects.
The program will furthermore perform correctly with Ellipses & Elliptical Arcs constructed in any UCS, and should be supported on all versions of AutoCAD, on both a Windows & Mac OS (since the program does not use Visual LISP).
