I now want to draw a tangent from the ellipse to a perpendicular snap on the line...
If I cannot get a "tangent" snap, I draw any line to intersect the ellipse. Now I can get a tangent, but not a TRUE tangent, just some point on the ellipse. If I continue drawing more and more lines as tangents, in the end I get the desired effect (it generally takes about six lines). Does anyone have any similar experience of ellipses?
BTW I know that I can draw an approximated "polyline" ellipse, but this is not what I want.
Many thanks
