How can I see vertical and horizontal dimensions of an elipse

[hugolopessilva]

Hello,

I have build a solid in which the projection of the hole on the face of the cube is an elipse. However, as I did not create the elipses on the faces, but the elipses are just the result of the projection of an empty egg inside an extruded rectangle on the faces of the extruded rectangle. How can I see the dimensions of the elipses? I tried to use the measure distance command, but with no sucess.

I´m attaching the model file,

Help appreciated,

Thanks,

This would be easier if you had modeled with obvious symmetry about the origin.
