Isometric circles in IPE

Hi,


Thank you for a very nice editor! Does anybody knows of a good way to
draw isometric circles in IPE? The easiest way would be if one could
just draw a circle inside a square an then transform the square and
circle into its isometric equivalent, but as far as I can find out, the
stretch-function only does stretching in one direction at a time?


Kindly regards
