ACAD: ATHENA produces an approximated polyline representation corresponding to the AutoCAD setting when the system variable pellipse has the value 1.
3M: Approximated polyline representation with three center points per ellipse side.
5M: Approximated polyline representation with five center points per ellipse side.
Note
Only "genuine" ellipses can be converted. These are produced when the AutoCAD system variable pellipse is set to the value 0. You will find further information about ellipses in the AutoCAD documentation.
