find Intersection and Point

[SimA]

Hello everyone

 

I'm looking for a way to find the intersection and the ring around the object.

 

After a few tries with Poly 3D and Nurbs I am now asking you.

 

Do you have a solution?

 

 

Thank you for your help

Can you be more descriptive as to the end goal? Are you trying to split the object? Are you trying to just find points?

points

 

1. I need the two points above and below.
Where the hand-drawn lines and ring cross.

 

2.I would also like to get the red ring with Marionette.

I could possibly get the ring from a nurbs surface. To do this, however, I would have to be able to reduce the modification points of the nurbs surface in a targeted manner.

 

Is my explanation OK?

I now find the points with trigonometry.

I still need the ring. Who has a simple solution ready?
