Adding a fillet to an elipse.

Hi
As something of a beginner here I'm try to put fillets into the corners of an ellipse, where the ellipse is bisected by straight lines. When I click on the ellipse I get the message "entity is not a line, arc or circle". Is it possible to do this? I need to be able to hatch the result.

Hi,
Try:
Safeguard copy EllipseArc on temp layer
Select & Explode EllipseArc
(see App Prefs for preferences to explode ellipses)
Do your stuff
Ellipses have No mathematical closed form solution, is done by serie expansion.
The workaround is to use a very close aproximated shape with arcs.
How close is up to you.

If you have drew offsets to Ellipses these will be splines.
No ellips is continuous parallel to an other ellips.

The tool is expecting a line, arc or circle for proper operation. If you click an entity and it isn't one of those you get that warning.

As a rule - yes. Maybe it needs a bit modification but it should be possible. To be certain we need the drawing as a dxf or dwg or at least an example drawing with a bit more information like radius etc.
