I have noticed that it is possible to create an engraved rectangle with "rounded corners" of a specified radius, but it does not appear possible (as far as I can see) to engrave a similar-looking pair of intersecting straight lines joined by a curved arc.
I suggest the addition of a "curved line" engraving tool, or the ability to pick a segment (angular arc of less than 360 degrees) from within the ellipse engraving tool. Possibly it could be similar to the curved slot tool, but a modification of the engraved ellipse parameters could provide more flexibility by allowing different major and minor axis dimensions.
