This part has no figure 8 cross sections either. The horizontal (ie parallel to
the Y=0 plane) cross sections all terminate with the normal to the curve at
right angles to the open face and the widest part of the cross section is always
at the open face, therefore all horizontal cross sections are "half elleptic
with the open ends flattened" - "half lozenge" is a possible description of the
cross-sectional shape

I can't, but then I don't have to as the part neither is a squashed figure of
eight.
For a lozenge horizontal cross-sectional dome see
