Yes I know, even if you turn the bicorn with respect to the X axis or with respect to the Y axis you get very different figures. Maybe I used my words wrong, sorry, what that inclined figure really represents is the envelope of a family of spheres and I chose the shape of a bacon turned with respect to the Y axis to wrap them. Thank you for your comments!!
Note: The family of spheres that do not appear here have in common that their center is on that inclined axis. Thank you again!!
