Well, maybe, sort of, kinda. :-)

Sorry, just kidding around. Punch drunk from lack of sleep. :-o

You can use the vlax-curve-getPointAtDist to help you out.

So if i understand you correctly  it is possible with writing a lisp routine but not with the standard AutoCAD divide command.

You can do this with the standard AutoCAD Divide command.

List the length of the ellipse
Draw a line that long and divide it.
Break the ellipse to give you the start point.
Measure the elliptic arc clicking on 2 of the points on the divided line as the measure distance
