Hello,<BR>
I need to mesh half ellipsoid laying in the XY plane on the minor axis a with major axis along the positive Z.<BR>
Based on the demo of the sphere I substitued the circular arcs in the Z direction with elliptic arc. (below the code)<BR>
Unfortuantely the result is not the expected one as the circular section in the XY cuts along Z are not preserved.<BR>
Seems that while for all circular arcs the ruled surface returns an actual quarter of a sphere, substituting with ellipses the resutling shape it's deformed.<BR>
Do you have any ideas for addressing this?<BR>
<BR>
Thank you,<BR>
