A new 'slice' kind idea...

[Dimitri]

'Finding the sheaf point from two flat objects'... it is near to what I said as an approach but it is not exactly the same thing... because the initial defining loops may not constitute necessarily a flat surface...

I am adding a new image below, illustrating the thing I am trying to say... as you see the loops, left and right, do not constitute a flat surface... so the 'sheaf' of flat surfaces concept can not apply to such a condition. Instead, the needed thing is having loops of equal distances between them arrayed in the space between the initial two loops...
