Inventor actually provides 2 solutions to an ellipse offset scenario.
1. If you pick the parent ellipse at or near a quadrant, the result is an
ellipse.This has no limit on offset-ability but the fact remains that 2
ellipses cannot be considered true equidistant offsets at all distances. To
see this, drag the offset to its minimum (flat) and see that its visually
not a true offset. These results cannot be converted to splines with a RMB
option after creation.
2. If you pick the parent ellipse approximately midway between quadrants
(like north east), the result is a true offset which is not truly elliptical
(will have sharp points). This offset has a minimum limitation where the
offset would become invalid. These can be converted to splines with a RMB
option aftercreation.
