Intersection between ellipses are not all detected.
This makes difficult difficult to make the projection as the example I give, where part of ellipses are to be removed betwwen intersection ponts.

Could you please attach the DXF or DWG file for testing or send it to us via e-mail? Thanks.
I tested this and drew something similar. I found that I needed to explode the ellipses twice in order to break them back down into arcs.I was then able to clean up the drawing with the modify tools!
I guess being able to snap to/detect elliptical 'arc' intersections before exploding them would indeed speed up the 'clean-up' process
I made some further tests.
If you draw an ellipse and copy and paste this ellipse the intersections are not found. If you re-size the ellipse moving and handle, then the intersections are found again.
My original drawing was done projecting 2 circles, so all ellipses are identical (direction and size). If you draw separately two ellipses exactly the same size and direction, then the intersections are not found.
If you re-size one of the ellipse or draw 2 different ellipses then intersections are found.
To summarize, intersection between two identical ellipses are not found.
