Bug - Cannot mirror offset ellipse

[SEC_CAD]

Inventor 2020: The attached part has a sketch of a circle, rectangle and ellipse. A 1mm offset is the applied to each shape. All shapes (including offsets) are mirrored about the Y axis. The ellipse offset shape is not mirrored!

This is causing me issues where I need to apply a clearance hole around an elliptical button.

P.S. This is day 1. I officially got Inventor 2020 pro today. I have been using the trial for the last month.

Hi! Indeed, this is a limitation in Sketch Offset command. An offset ellipse in Inventor is a special curve. It is totally driven by the offset source curve. After you mirror the sketch curves, what are you planning to do next? Extrude them? Couldn't you mirror the feature or the body instead? What is the purpose of mirroring the sketch?

Many thanks!
